Ciao, Signor Massimo.

Is there any possible problem to connect hifi Box 300 and 650 professional together on R35 or v7200 if equipment is valid?

My R35 burned out after 10 years playing with Box 300 & 650(no professional). It happens 15 days after i replaced 650 with 650 professional, so i connected another Grundig receiver, and I’ve lost left channel after one hour of playing. Could it be because invalid 650 professional or it is just bad luck coincidence?

Thank you for your time.

Ante, Croatia.

Hi Ante

Probably only bad luck

Massimo

Dear Massimo!

I have one question for you:
Did you listen Grundig FineArts set - I mean top series 9000 and 9009 – CD + amplifier + loudspeakers?
What is your opinion about sound of this „highest” (price and look) series of Grundig?
I have v1700+CD7550+Box650Prof but I have so far no opportunity to listen to this top series od FineArts.
Thank you - best regards - Artur

Dear Artur
I'm sorry, but the FineArts series has nothing to do with sound quality that made Grundig products from 1974-1985 so different from all the others. In 1984 Philips joined Grundig and the audio design team was directed to the video sector. An exception are some model that remained in the catalog for a few years but unfortunately the FineArts series has nothing to do with the CCI project system of the golden Grundig period.

Best Regards
Massimo

Dear Massimo,

Thank you for your answer. I suspected such answer ;) but I am interested how much or how big is the diffirence because many peoople (audiophiles) are thinking that CD and amplifier 9009 series (FineArts) is the best achievment of Grundig sound and technology. That wy I asked you - did you listen to set of A-9009 and CD-9009 and your opinion. Did you hear such a set?

Thank you very much!

Artur

Dear Artur
I know the real causes of sound and I have verified them on many many occasions over more than thirty years of design works. For this reason it is enough for me to see a device without a lid to see if it has any chance of good sound. But if you have this conviction about the FineArts series you are right to follow it, sometimes personal beliefs have the upper hand over listening.

Greetings
Massimo

Thank you for your answer.

Dear Massimo - I know - CCI for you is nothing special - you know it by hart or you look on photo and you can tell me about sound of this CD and amplifier everything ;-)
I am not able.
I am interested how do you know that Grundig A-9009 and CD-9009 does not sound good?

I understand that you did not listen to such a set in real life.

For me it is amasing and it is a magic that you know the sound of amplifier by looking into picture!
How is it possible I do not know.
I can uderstand that you have circuit plan of all elements (transistors, capacitors etc) and reading drawing of circuit connections you can tell me something about its sound but NOT by looking into picture/photo of the equipment!

How can you say its sound is weaker than v1700 without real listening session ?

I am very interested because my coleague invited me to compare my set (v1700+CD7550+Box650Prof) with A-9009 and CD-9009 and I would like to know someones opinion but after real listening session.

I admire your listening experience and achievments in audio! I also thank you for your advices on your site about Grundig. It is big suprise to copare Grundig sound with set high-end worth 100 000 Euro. Very often Grundig wins ;)

Please explain me how do you know that A-9009 does not sound good?????

warm greetings - Artur

CCI = Circuit-chassis interface

In the meaning of this acronym lies the answer to your question (that facts can demonstrate).

Make your comparisons (by disconnecting and putting in another room the electronics that you don't listen to) and you will realize by yourself that my words have foundation.

The problems are not in the circuit (only partially responsible) but in some boundary conditions.

Massimo

Hi Massimo,

The MA10tp is well working ! Very performant amplifier, such a Grundig, but more detailed, transparent and dynamic ! Congrats !

I just need three advices :

- regarding the Box 300 connection, should I cut the current cable with the Din plugs or build a kind of Din cable with a female connection behind the amplifier and let the Box 300 with the Din plugs  ?

- my ps1020 has a cable with two Rca, you mentioned that the Din input is better...should I use an adapter Rca/ din or use the Rca inputs?

- I have both cd35 and cd7550 ...and the cd35 seems more alive and dynamic, may be less neutral. What is your advice between this CD players ?

 Thank you again and Nice weekend Massimo 

Hi Frank

Thank you!
To connect the boxes 300 if you do not want to cut the cables, you need to make an adapter with a din female point-line and 15cm of cable type Norstone CL150. However, for better result,  put a small ball of plaster (like the one on the box grids) over the joint of the two connectors, later I send you photos with an example.
For your ps1020 can you send me pictures of the cable with connectors? Standard connector in ps1020 is a DIN connector.
Between cd35 and cd 7550 I advice the one less tampered with over time ... trust your ear.

Best Regards

Massimo

Hi Massimo,

Just a question, I use the LT with three equipments connected : cd 7550, PS 1020 and a tuner 7500...

Somewhere, I have the feeling that the high frequencies are more "aggressives" when the tuner is connected to the LT amplifier (even if the tuner is "off")... or more soft if the tuner is not connected.

Is it in my mind ?

Thanks

Best regards
Franck
 

This is correct…when you connect others source, the quality worse. For best quality you must connect only ps 1020 and cd7550 to inputs. This is not a caracteristic of LT amp but you can verify the same comportment also with all Grundig amps (or others very transparent amplifier like these...if only they existed)  J

Regards

Massimo

I'm not crazy ! thank you. 

Can I keep 1020 and 7550 connected in the same time or should I connect only the source I use ?

Thanks Massimo

Frank

If you have ps1020 or ps1020a with original shell, original Shure M85G and N91G needle, you can connected in the same time. A little worse the ps1020b.

Massimo

Thanks, I’m going to send you a photo of my 1020...really special with RCA connectors (really seems manufactured with). A or B I don’t know, I have a Jico needle....I’m quite sure that you will explain that it’s also better to remove the supply of equipments we don’t use, no ?

On rear you can see the exact model. Listen your cd player and try to disconnect turntable…

Massimo <>

Good morning

I have Pioneer TAD speakers with TD-4002 medium and high drivers, and TL-1601 for bass.

Very different sensitivity.

My room is about 80sq/m.

To amplify speakers, I have Grundig XV7500, and two V1700 amplifiers as power amplifiers.

To control difference in sensitivity, I use preamplifier output volume control.

Questions.

Should I change V1700 for Linear Transfer amplifier?

If yes.

It is possible to use only one amplifier, solution that I prefer for economic reasons?

If yes.

Which one?

How to control different sensitivities?

If your answer is two amplifiers, which ones?

Best regards

César

Dear César
If you have a passive crossover but there is no attenuation resistance on the tweeter, you need to pilot the two speakers with different levels using just two amplifiers. What choose according to your needs is difficult to advise ... you can choose a hybrid solution with a V1700 and a LT amp or the solution with two LT amp. I would exclude the LT MA100 given the efficiency of the speakers. I think a MA50 (or two if you want to do the pairing) can be fine.

Best Regards
Massimo

Dear Maximo

First: I’m pleased with my sound, thanks to you.

Is with you that I find Grundig magic.

Second: my problems are minor ones.

1: use integrated amplifiers as power one, makes bubbles in my head.

2: such a lower power output makes even more itching.

Crossover have a l-pad, but I do not like l-pads: I think de-gradate sound. I had bypassed it.

Use only one Linear Transfer power amplifier is a good solution: if you find a way do deal with different sensitives.

Third: You recommend RCA interconnect cables; speaker cables; and power cables.

What about DIN cables: and DIN RCA cables: what do you recommend.

Where can I buy cables you recommend.

I would like to be sure that my equipments are in you recommendation state.

There is any possibility, that you please verify it and rectify?

Best regards.

Cesar

Only one Linear Transfer power amplifier is a good solution: if you find a way do deal with different sensitives.

Without l-pad is not possible find a solution for drive with a single amplifier two speakers with different sensitivity.

The cable rca that I recommend is supplied with the LT amplifier. You find the recommended cables on my website anyway

http://motxam.interfree.it/Atruths.html

Dear Maximo

If your are in my place what you do?

Is it possible to improve my sound, assuming everything is installed with yours recommendation?

Is it possible with only one Linear Transfer amplifier amplifying both drives, with L-pad??

Should I use, Linear transfer amplifier for bass and V1700 for medium and highs?

Should I not buy anything.

Should I buy 2 Linear Transfer amplifiers: and I only do, if you guarantee a big improvement in sound quality?

Please tell-me what shall I do?

Another point: could you do me a favour, and check all my equipment to see if everything is alright?

Best regards

César
 

I have seen your video, I have some question:
1) Do you use LP only?
2) Turntable and pick-up models?
3) Your speakers system is an original TAD or DIY with speakers TAD?
4) What are the features that you would like to improve on your system?
5) Are there "fixed components" (components that you would not like to change)?

Best Regards
Massimo
 

Dear Maximo

I try to answer yours questions.

1) DO YOU USE LP ONLY?

No: I use LP, and digital.

Where electronica are, you can see, in right looking size, a OPPO Blue Ray player.

I play DVD and Blueray films and Opera: and on top is a TV box, that is connected to OPPO.

OPPO is connected to CD imput.

I use same input to connect EMT 948 and EMT 930, that are on the hole on far looking right.

948 and 930 are connected to a balanced split box that is connected to preamplifier by a Balanced/RCA cable made by me with BDC cable.

Usually I connect OPPO to CD imput: Rarely, I like to ear EMT: so I disconnect OPPO and connect balanced box.

I do not play very much OPPO: but I play much computer music from a computer that is in front of me

Computer is connected to a small DAC that is located in same shelf where bass V17 is.

DAC is connected to preamplifier to Tape 2.

Note: I have same inexpensive small DAC that I change often. 

Now is MUSE playing.

2) TURNTABLE AND PICK-UP MODELS?

Long answer,

Some years ago, I have opportunity to buy radio turntables for nice prices.

So my ex-wife uses to say, that prefer that I collect stamps instead of turntables.

I refer some: not all.

Sony PS-X9: with Shure M75GT2 is playing right to preamplifier, connected to Tuner.

EMT 928: I like it very much: is on far left, playing with Stanton 500 cartridge: I like it very much.

Is connect to tape 1.

Garrard 401, Gray clone tonearm, with Shure M44G: I like it very much.

Is connected to phono MM

EMT 930: I have 3: with 155, 153 stereo phono stages, and 139 mono phono stage: I'm going to sell it: at lest 2.

Playing now, on far right corner is 153 phono stage one, with EMT TSD cartridge.

EMT 948: with Shure SC35C: I like it very much: on far right.

This are the ones that are now installed.

In medium, every moth I change some models, and install others.

These are some.

Thorens TD 124

Thorens TD 135: I like it very much.

Techics SP 10 with 2 arms…

Grundig 1010: 2

Grundig 1020: 2

I like Grundig turntables: but in my system, they make some feedback.

I hope that you tell me how to fix it.

And much more, like…

Toshiba SR50

Teac with floating suspection.

Lenco: almost all models….

Dual: some models.

And……

3) YOUR SPEAKERS SYSTEM IS AN ORIGINAL TAD OR DIY WITH SPEAKERS TAD?

I bought boxes and crossover in Hong-Kong, and install TAD drive.

4) WHAT ARE THE FEATURES THAT YOU WOULD LIKE TO IMPROVE ON YOUR SYSTEM?

I had said: I like very much my sound: My infelicity are small: integrated amplifiers working as power amplifiers: and 17W in each amplifier.

Is only head problems, more than sound problems.

But of course: If I have opportunity to improve sound quality, I would be much pleased.

5) ARE THERE "FIXED COMPONENTS" (COMPONENTS THAT YOU WOULD NOT LIKE TO CHANGE)?

Not: not one.

Some years ago: I was a furious turntable connector.

Not now: I could sell al turntables and more.

Best Regards

Dear Cesar
Your turntable collection is impressive.
I know many of them and I appreciate some of your choices.
Another questions to get a clearer picture and to tell you how I would move in your place:
1) With which other speakers did you feel comfortable in your room before the TAD?
2) Do you have a complete Grundig ps1020 with mat, original metal band, 45rpm adapter, Shure M85G + N91G available? If yes it's a ps1020, 1020a or 1020b (see rear panel)?
3) The more frequently source that you use is the “liquid” music from pc (correct?) and when you want obtain the top quality you connect turntable, it’s correct ?

Best Regards
Massimo
 

Dear Maximo

Sorry for my late answer.

Answer to second question:

I have spent all day looking for my PS1020: I could not find it.

Is somewhere: but in a difficult somewhere.

I have find 3 Grundig PS 1010, 1 Saba 900: direct drive turntable, very similar to Grundig PA1020: but PS1020 nope.

I have 2 Shure M85G, and N91G and N75GT2 available.

Answer to first question.

Before TAD speakers I have a very different music disposition.

I have a Martin Logan speakers in back, on door right.

Answer to third question.

Correct.

Dear Cesar
I understand that the TAD system is to your liking in your environment but maybe you have not tried something alternative. A Grundig that could adapt to your location is the box 2500a (with installed grills) on Bose stand. It would be a test to see if the TAD is irreplaceable from you or if we can consider an alternative that can be better and that would allow the use of a single amplifier. The 2500a is not to 100% in your room (the near rear wall would be necessary) but I think they could still fit well. Other two speakers that you should try are the Audiorama 8000 and IMF Super compact 2.
I personally believe that your speakers are not irreplaceable and in my opinion this is an aspect to be evaluated but unfortunately we are separated by many Km. Alternatively also the Aktiv box 30 you could try but to have them full CCI is need the modify.
The aspect of the CCI that is always very difficult to transmit is the need to galvanically separate the full CCI devices from not CCI devices to achieve the best results.
For example: if you try a Grundig PS1010 with all the accessories (original mat, metal band, 45rpm adapter) + original shell and M75B + N75gt2 head and you really want to hear its potential you can not connect it with other turntables (or others source) to the XV7500 but this must only have full CCI devices connected. Otherwise the sound of the turntables comes to level transparency downwards. The other devices in the room should be disconnected from the XV7500 and from 220V network. Obviously you can not put off the television or anything else but what is possible, among the devices that are rarely used anyway, would benefit. For example, if you leave your DAC or OPPO connected to the XV7500 while listening to the PS1010, it will get significantly worse.
Another solution that would benefit is to use the XV7500 with its T7500 Sinto using the 6-pole DIN cable (a central pole that carries power for the relay) and taking care to turn on the pre from the power button of the sinto. The improvement in this case is quite net.
As you can see I did not talk about amplifiers ... if I were in your place I would start to try the above solutions.

Best Regards
Massimo

Dear Maximo

Before we go to finally, slowed me some question.

1) Why do you prefer for my room, Aktiv 30 insted of Aktiv 40?

2) Why do you think such a small speaker like IMF Super compact 2 is suitable for a large room as mine?

I have a pair o Monitor Audio 700 gold, that I like very much: they are similar in size to IMF: and I had never consider use it, for size reasons.

3) what tuner to buy T7500 or T7500a: they are both selling on Ebay

Let´s finally.

PLEASE TELL ME WHAT I SHOULD DO.

After reading what you said and your site, my wishes are:

I would like to have a full CCI system.

And I would like to have other system to play computer music, OPPO, TV, and other fancy turntables.

A cording to you I think is possible.

I have one electric phase connected to power box, that I use only for music.

Could that phase be used for CCI system?

And wall power be used for other system?

I have Akiv 30, Akiv 40 and 2 XV7500.

And now please tell me what shall I do.

If you say Akiv boxes are better, and that I should send my equipment to you for full CCI modification: I do.

If think that is better, for me to buy an Akiv box with CCI, that you already have, I buy it

If you consider other solution better just say, and I try to find money to get it.

You just say: and I try to do it.

Best regards

Cesar
 

1)    Aktiv 40 (and aktiv 20 and 30) reach their better result on BF4 support (12cm height) but in this way the height of the tweeter is probably under your desk. On 45cm stand Aktiv 40 has not a good sound. I forgot the Aktiv50 which is probably the best aktiv solution for your environment. But if you have aktiv 30 and 40 you can try and tell me your impressions. I think however that in your room the Grundig aktiv solution is not the better solution for “height problems”. The guilty is  your desk J. For this reason I advice to test Grundig Box2500a (many different to aktiv 40 in bass frequency) that reach his better result on 45cm stand.

     2) Do not confuse imf compact (two way) with super compact (three way). The aperiodic system of them I think it should give a good result when lifted with 45cm stand in your room. Not a great bass extension but sure a good balancing.

3) Only aesthetic differences, T7500 is more beautiful :-)

I would like to have a full CCI system.

PLEASE TELL ME WHAT I SHOULD DO.

I can help you to build a CCI system in your room but, like the root of a tree, the correct choose of speakers for your room is THE FIRST step to go through.

Your location is not easy because normally the pneumatic suspension speakers needed the rear wall near or the floor near.

My advice is : test Box2500a on Bose stand and test IMF super compact 2 on same stand. If one of this reach a better result of TAD we can proceed to other step.

We need patience and method, first we need to understand how your room reacts with some speakers…

Best Regards

Massimo

Dear Maximo


A big thank you for your time.


First: you say for me to try Grundig 2500a and IMF super compact 2 on Bose 45cm stands?


So : I should buy it.


Please inform:


Have you any of this items for sale?


If yes, please inform price, including shipping costs to Portugal, and way to pay you.


If not: I must look at Ebay, or similar site.


Second: could you please check my Grundig equipment, to see if it is according to CCI standards?


If yes, please inform address and price.


Third: I’m going to do everything you say: I’m sure we are going to get very good results.


Best regards


Cesar

>First: you say for me to try Grundig 2500a and IMF super compact 2 on Bose 45cm stands?

Yes

>Have you any of this items for sale?

Sorry, I haven’t to sell.

>Second: could you please check my Grundig equipment, to see if it is according to CCI standards?

Like you can read on forum (http://hifi.altervista.org/viewtopic.php?f=7&t=2 ) from October 2013, due to lack of time, I check only the Grundig apparatus that I supply for completing LT system.

>Third: I’m going to do everything you say: I’m sure we are going to get very good results.

The choise of speakers must be do with attention….from this dependent all the follows steps.

Best Regards
Massimo

Dear Maximo

Life is so complicated that there is not need to complicated it more.

My original intentions is to buy a Linear Transfer amplifier.

We starting talking, and in the end you suggest that best for me is a CCI system.

I agree: let’s do it.

I have a lot of Grundig equipment: all suggested in your site.

You say now: you need more equipment: you say witch and suggest how to use it.

I agree.

Now.

The mother of your recommendation for a full CCI system is equipotent strictly according to CCI rules.

How do I know that?

Only you can tell me.

If one equipment, only one equipment is not according to rules, no more CCI system!!!!

I can buy speakers you suggest, install it accordingly what you say, and sound is terrible.

Why?

Equipment that I bought here and there is not according to CCI rules.

So: for me: the mother of rules to have a full CCI system is to have correct CCI equipment, installed according your’s rules.

Am I wrong?

Only one person can check equipment installed: that person is you.

If you say: buy a Linear Transfer amplifier: I buy it.

If you say: buy Linear Transfer speakers: I buy it.

Please: just say: I believe on you: but please again: let’s be sure that everything is according to CCI rules.

And only person can guarantee that: that person is you.

What can I say more?

Best Regards

Cesar
 

Cesar

I am available to help you for reach a good CCI result but the CCI check of your apparatus is not the first priority at the moment. When you have found the better speaker for your room we can resume the speech and choose the best path. I am not a "seller" and I do not want to advise you by making you buy things that I have but which I do not consider suitable for your situation. Be patient, yours is a particular enviroment and there is need of some experiment. Then we'll see the rest. If you want my help I need to understand how your room reacts with speakers I know. A good indication could also come from the aktiv 30 you already have at home: could you describe the sound you get by replacing them with TAD?

Best Regards

Massimo

Dear Maximo

This weekend I had installed Grundo Akiv 30 near the wall, as showed on photo.

Impression: very, very good: very impressive…..

Problem: Sound on TAD comes for all back wall: you have a complete orchestra in front of you.


I have two strong, very strong supports: you can see on photo.

Should I use it?

Please tell me what to do next?

Best regards

Cesar
 

>Sound on Aktiv 30 comes from two holes.
>Can I do a better installation?

You must remove the TAD when listen Aktiv.
Have you insert feet under aktiv?
Leave the right speaker parallel to wall, the left is correct like photo. You have setting the channel on rear pannel of aktiv?
How much is the bass extension?
Hight of your stand?

(many others e-mail are follows but are not of common interesting)

 

Good Evening

Please inform price for Linear transfer power amplifiers.

Thank you

Cesar

Hi Cesar
Linear transfer power amps price are the follows:

MA25: 2200 Eur
MA50: 2500 Eur
MA100: 4000 Eur

Integrated MA10tp: 2500 Eur with phono
Integrated MA10tp: 2000 Eur without phono

Hi Massimo,
What do you think if I spraying paint on SL1000 body? Will it significantly ruin the sound? Or shall I use certain paint?
Is it enough to drive SL1000 with V20? I really love V20 sound.

regards,
Jioe

Hi Jioe
It is not advisable to use acrylic spray paints but only two-component paints that have greater adhesion and rigidity.
Only you can see if in your room the v20 is enough to drive the SL1000. :-)

Regards
Massimo
 

Hi Massimo,

What kind of paint the two components is? I dont really understand. Can you be more specifiic?

Is that some way SL1000 would be better than Box300?

Box300 already has incredible sound..

Regards

Jioe

Hi Jioe
I don’t know the composition of two components paint…it’s a professional paint for wood.
SL1000 need particular installation with four wall near to speakers (under 1,7m). It’s a loudspeaker that need a small room and a lot of patience for reach the better result.
But this can be over all traditional loudspeakers

Happy new year to you!

Massimo
 

Hi Massimo,

I want to install it in my small bed room, around 2.8 x 4.75m, where I will put it on the wide side. Each left and right of the tv. I plan to make it close to the rear wall of it. Just like my Linn Kan  needs a back wall on my pic attached. Do you think it is correct?

Regards

JJ

Yes. There are necessary (probably) two paintings in wool as acoustic absorbers to put behind the speakers. Like these: http://motxam.interfree.it/notaresco.html

Hello, Which floor standing speaker do you recommend? Grundig 1500a or Grundig 2500a?

Hello Will
The best solution is always dependent to room dimension and type of installation.
I can advice to read with attention the loudspeakers installation:

Hello Massimo,

My room is about 11 feet by 13 feet. Do you think the 1500a is better than 2500a? Do they both sound the same? I have several Grundig speakers, and they all sound very excellent. Why do Grundig speakers sound better than most other speakers?

Thanks, Will

All your questions are answered here http://motxam.interfree.it/

Read with care please.

Massimo

After reading this article on the website:

http://www.grundiglove.org/grundig-v1700/

I understand that the loudness control can never be switched out of the circuit!

And the V1700 was a faulty design in that is caused damage to loudspeaker tweeters.

If both are true then surely this cannot be a very good amplifier - yet you say it is? Please help me understand.

George

Dear George
The loudness (when switched out) is not present on the V1700 because the mentioned network C708-R710 simply inserts a 1Mohm resistor parallel to the input (before the volume control) above 1000Hz and this, if the source that pilot the amplifier has an impedance lower than 10KOhm (as it normally happens) it does not involve any variation on the frequency response. Absolutely unfounded also the possibility of damaging the tweeters that is common to all the amplifiers when used in clipping. The only true limit of the V1700 is the sizing made only for nominal 8Ohm loads, which therefore forces attention to the heating when driving loads of 4Ohm otherwise it may break the amplifier and in this case the woofers (not the tweeters…) are also at risk.
The site to which you refer, founded by people without any technical expertise (ex members of our forum), reports many mistake as it is voted to combat the advice that for twenty years are present on my website. The network is unfortunately also this, a mixture of pride and envy. Care must be taken.

Massimo

Dear Massimo what are the binding posts on your amp? Power? Integrated? Din or bare cable?

Pawel!

Bare cable.

Regards

Massimo

Hi Massimo,

I hope you're fine !

I have a topic which is not very clear in my mind : the position of the cables !

Wheter or not the amplifier is on the ground, should I :

- put the cables on the ground ?
- put the cables on the ground with a carpet below ?
- hang up the cables ?

I currently put my cables on the ground (my Receiver also) but it seem's that if I put something between the cables and the ground the sound seems quite different !

Thanks in advance for your advises,

Best Regards
Franck

Hi Frank

All ok thank you

-Speakers cables ever on the ground

-Power (220V) cable of receiver on the ground…all others 220V cable with carpet below

-All signal cables with carpet below

I have a few questions. I hope that this is not a problem. I have a Grundig v 1700 Grundig box 650 prof, the original speaker cables Grundig (I also have a "vivanco hpfl 153 '5 meters), Grundig CD 7550 and the original Philips cinch.

I wonder if grundig box 650 should be on the BF1, or better on the counter. (As far from the wall). In your opinion, is better speaker cable grundig or vivanco? Is a good idea to make a cover of cotton to the speaker cable?

Marcin

Hi Marcin

It’s missing one information: how much the distance from your ear to wall behind you ?

Original Grundig cable is better that Vivanco, and better is listening box 650 with grilles…

Regards

Massimo   

Distance of ear to wall behind is 1 metr. 

Box 650 pro can BF1 to listen to, or better on the shelf?

Better on BF1 very near to rear wall but with drappes on this wall (see photo of italian forum here for example: http://hifi.forumup.it/ )
In your room will be better 850a and 1500a.

on your side in the technical tests, we can see that the V1700 should be +1 +1 bass and treble. Is the system of box 650 professor will be the same as the box 400?

“no carico” mean with box400 disconnect
“con carico” mean with box400 connect
V1700 should be +1 +1 bass and treble ever

Hello Massimo.

Maybe for you  is little surprising is I heard something about you 😊

I heard many good things about vintage grundig system, so decision make one for myself.

So far ordered amplifier Grundig Fine Arts A9000 and V1700 also bought from you cd 7500 ver.1

At this moment have  Dali 505 2 way 4 ohm speakers  92 db efficienty.

In future want to buy grundig 650 pro,850 pro or 1500pro speakers. But I need time to find somewhere in good condition with good price. I don’t know yet is it room which

that system want to put in,will be between 20 or 30 square metres. I not sure yet.

I suppose is v1700 could be to week for Dali that is why bought A9000

My question is:

A9000  probably still fitted oryginal STK3102 ver.4 (not coming yet) is it big risky connecting.

Dali. What is your opinion and what I could to do best at this moment?

Regards Darek

Dear Darek

A9000 is’t a CCI amplifier and sound very worse respect V1700, V7000, V7200 etc…

With your Dali loudspeakers you can use V7000, V7200 or V35 or some receiver “large series” Grundig…but when you know the room dimension I advise to search immediatly a right Grundig box.

Also use V1700 with 4 ohm speakers but not with high listening level…

Hello. I am your big fan of Polish.

I am a happy owner of the system GRUNDIG (v grundig 1700 CD 7550, the original cables)

Now I bought a wonderful Telefunken tl 800. Unfortunately, I had to replace some speakers (tweeter and woofer). After disconnecting the cables I do not mark it. Do you have any photos of the interior?

greetings

Hi Marcin

Do you find here the schematic: http://hifi.forumup.it/post-30915-hifi.html

Regards

Massimo

Hello. What is the best amplifier to TL 800? Grundig v 1700 is probably too little power. Maybe grundig v 7200? Or maybe something from the stable Telefunken? Telefunken 6040 opus? Maybe some sansui?

Hi Marcin
Tfk amplifier are not CCI…V7200 is good or also V7000 or some receiver Grundig 20-25-30-35 etc.
Regards
Massimo

Hello Franck

The difference is partly in the linearity and partly because a LT amp is a NEW full CCI amplifier...
Objects that are 35 years old are often with chassis/circuit not like original CCI condition...and this cause a worse sound.

Dear Sir,

  I have a Grundig setup. V20, V35 CD, Grundig Professional 650. Please, let me know if you can apply a CCI [partial or full] modification for an external DAC, in this case Lavry DA10, for a full CCI solution.
  Many thanks in advance.

Good morning,
Unfortunately my cd7550 is quiet this morning. In the midle of a song, the 7550 stopped to play.
I know that we can may be fix it, but for the moment it's paintfull ! I cannot listen music..
I'm a grundig lovers and leaves in France. I wonder if You can sell me a lt cd player in order to replace my grundig.
Thanks in advance
Regards

Franck xxxx

Dear Franck
I modify several cd player models with CCI implementation. You can choose a model and the modify cost (independent of model choose) is 500 eur. The result is the same (if frequency response is flat...) a full CCI cd player (and with remote control!).
I advice like basic to modify some models of Marantz cd player like (for example) this http://motxam.interfree.it/cd6004.html

Regards
Massimo < id="table76">

Dear Massimo is grundig box active 50 as good as 40 and 30?

Pawel.

Dear Pawel
On Aktiv 50 must doing a little modify DIY for improve it and reach similar result like aktiv 40: the frontal grill is fixed to box with 6 pressfit grill-guides...you must remove (from grill) the two pressfit present in middle point of grill.
However I advice the aktiv box only with CCI mod...there is a big difference...you can find comment on Italian forum...
Without mod CCI I advice much more the passive solution.

Hi,
I'm very fan of grundig speakers, I own two models: super hifi-box 650 and 850.
Recently I read on polish forum that the Stands BF3 are highly recommended for 850 type.
Unfortunately I am not able to buy it. According to me it is possible to DIY.
Could you inform me how it should be done? material, dimensions, etc.

Thanks for your input,

Gauthier

Hello,

Just to share something with you.
Yesterday i went to visit a high end audio shop in The Hague (Netherlands) to listen to a 150.000 euro hifi set and Pink Floyd Dark Side of the Moon.
The guy who owns the shop also has a Pink Floyd band and he played last evening at the Peace Palace 100 year opening event, which was really good..
However, i listened to the whole record in the shop. Although the sound was good with a wide, deep and high soundstage, it sounded compressed especially for mid/high frequencies. The high hat determines the whole timing of Dark Side of the Moon and it sounded flat and distorted.
When i came back home i listened to the whole CD on my Aktiv 50 Professional, CD 35 set up (no Grundig preamplifier yet unfortunately) and the difference was like day and night.
My setup has cost me about 200 euro and it beats the 150.000 high end set (see picture) hands down. The difference is in musicality and especially emotion.
The other difference is that the audience of people in the room didn't express any emotion at all. The live concert was much better!
Now i am going to invite the owner of the shop to my house and let him listen. He is a very nice guy, wonder what he will say.

Ciao

Hi,
I'm very fan of grundig speakers, even if I own only two models: super hifi-box 650 and 850.
I just opened the 850 to check the crossovers, and I was very amazed by the quality of most components of it, especially selfs, that are big and nice built. But capacitors are from Frako, which is definitely not the best caps you can find... so I was intending to replace those, because I really like a lot those speakers, but I think they could sound even better once recaped.

And I found your website, and the mysterious footnote, warning that one never should modify Grundig products... so what about recapping the crossovers?? Any specific reason not to do so? I did this already one several other speakers, with great results...

Thanks for your input,

Gauthier

Hello Massimo,

I want to ask your advise.

If I'm using Box400 on stand (no other choice), a metal stand for Linn Kan, what distance from front wall should I place them?
Room length 4.8m, wide 2.85m. I have V7000, V20 and V1700. In your opinion, which one result the best?

Thanks,
JJ

Dear Jioe
Box400 are not for stand installation but only for bookshelf installation.
If you want test a two way Grundig to stand you can find box450 (or box550) first series (not professinal).
Differences between CCI Grundig amplifier are dependent more to condition of every one.
Regards
Massimo

Dear Massimo,

Why do you say Box850a, Box1500a, Box800, Box1000 are stand-mounted speakers? I have Box850a, but I use them as floor-standing, for I don't have stands. Is there a big sound difference between stand-mounted and floor-standing Box850a? Should I make stands for them and how? Can you give me more details please... Amplifier I use is V7000. Thank you.

Best Regards,
Predrag

>The updated amplifier arrived today. I have connected it and played

hi Dear

I have been through your site number of times, just to understand how deep you were involved in doing research with all these audio components. Actually I do similiar to something what you are doing, but difference could be the price of stuff you deal with (you amps and preamps looks much more expensive).....anyway. With your advice (in the website) I just brought V30 (ofcourse grundig) to try. I was amazed......the quality of sound it was producing was never heard before.I compared it with all my previous ones, luxman, yamaha, sony, marantz even Nad, nothing could stand against it. I am planning to buy SXV7500 and V1700. The only problem I face now is I REALLY NEED a remote control with volume, which these great devices do not have. do you have any suggestion to (somehow) get the same You never discussed V1 or V2 or R1 or R2 ......or FineArts by Grundig. Are they good as well?? Looking forward to hear from you!!! Regards Bandeep Singh Neuenhof Switzerland

Dear Sir For remote control on CCI system you can find one RPC600 or RPC650 .

Fine Arts is not good (not CCI)

Dear Dusan

if your local Grundig service is going to service your CD7550 please be sure that disassembling and re-assembling will be done exactly

and carefully at the same way. I usually check only the V7000 amplifier for full CCI implementation but I do not service any Grundig components.

A full CCI system can sound more natural and rich in harmonics comparing to the other hifi systems. If you need, I can supply cables to you.

Dear Dragan
Your speakers (of box300 and of box650) are in perfect standard condition, no defect.
On rubber of box 300 is a standard anti-humidity treatment and PLEASE DON'T TOUCH IT !!
Check only if your boxes have a good air sealed: push (very gently) on center of woofer, when you release, it must return very slowly to normal position if no air loss.
if it's ok , insert the grilles and install box 300 very near to wall and ON BOOKSHELF (no more height of 60cm) or supported on a pair of box2500 (used like stands).
Box 300 needs a very little room for a good performance in bass frequency. Also your listening point must be no more distanced to 40cm to rear wall.
Best Regards
Massimo

Dear Massimo!

After completing two whole CCI systems my conquest for perfect sound stopped abruptlyJ . Seriously speaking I had the best time in my life in terms of musical experience (since the turntable came last year). I never had really chance to say THANK YOU!.

I was in Livigno this winter but had no time to travel any further. But one day I will visit you in person and will get some of your amps and speakers. I was moving around a lot with the speakers (the 850 upstairs sounded too different than 1500 in the other room) but finally I found the “SPOT”. They were just tilted forward too much, after changing that - no more differences (just the right ones!) perfect space and vocal and highs etc.....

One more business question – would it be possible to get modified DVD from you, we can agree which model, but this way I will spare the shipping cost from Poland to Italy/ let me know if this can be arranged.

To make the long story short thank you again. I may one day put some more thoughts about my experience on the forum but it seems to me the forum slowed down a little recently.

I hope I can be in touch with you guys. Regards! Ciao! Pawel.

Dear Pawel
How are you?

The CCI mod on DVD player have a cost of xxx eur and shipping cost for Poland with air mail is about of 50 eur.
I offer ever inclusive in this cost a singolar opportunity: in case of serious breakdown (laser) I move free of charge the modification CCI on other dvd player for one time.

Hi Jae
Tracking
force is the same (0,75gr) for better sonic result.
You can increase to 1gr or 1,25gr for better tracking but with a worse of sound

Dear Sir,

Searching on the net I found your wonderful website and I really amazed.

My request is the following to you:

I bought a Philips CD 960 player few days ago ( looks like a new one) and I am very impressed by the nearly analogic sound. So I am using the same Philips CD 960 now as you do, but without modification. I think there are more possibility in this player, but I do not know how to start with the modification. I am a little affraid, If I modified it I am going to loose the nice sound.
I would like to ask you if possible to send me some inside photos and detailed description about your famous linear transfer modification. I would be really thankful if you could help me.
Thanks in advance again.
Yours sincerely,
Tamás


Dear Tamas
Sorry but the LT CCI mod. is a proprietary implementation and I execute only in my laboratory.
The cd960 standard is far to analogic sound, if you want listen a CCI cd player with small cost you can buy on ebay.de a cd 7550 or cd7500 Grundig....You can listen which is the mean of “analogic sound”.

Greeting from Romania,
sorry to disturb you,but i have a few question.
I own a pair of Grundig box M600,wich i have tryed to drive them with a Rotel 840 bx 4(doesn't sound so good, missing the low freqvencies),the best that drive them is an old Korting A100.I was studiing youre site and i have the folowing question:
1.The amplituner Grundig RV 5000(or R5000) will drive them better?(i'm asking this because i don't have the chance to listen,only to buy from the internet).
2. In this moment the pair of Grundig are mounted on stand and they are 1m away from the back wall and 30 cm from the side wall,and there is no chance to put them in to a bookshelf as you sugested.The option would be mounting them on the wall(they have some holes left for this purpose,i belive).Do you thing it is a good ideea?

Best regards
Adrian xxxxxxx

Hello Adrian,

1. The best Grundig amplituners are the R20, R30 or the old Receivers 20, 30, 25, 35. But you can also look for R1000 and R2000. The high powered models like the R5000 are a bit worse.

2. Do not mount the M600 on the wall. Try to lower them near the floor if needed.

Regards
Massimo

Yes
There are exactly three version of B&W DM6 The first with woofer control level, wood front panel and all yellow midrange.
Second version
without control level on woofer , plastic front panel and all yellow midrange.
Third series without control level on woofer , plastic front panel and only cone yellow midrange.

The best is the second series,
the worse is the last series.

>You say that the Dahlquist DQ-10 are

Not equal but similar quality with
many differences......

that the DQ-10 are a little "light" on "base >department" but my
experience with the B&W DM6 was different, the "base" is fantastic
(they >were placed near the back wall)... i am confuse now...

If you
intend the "bass department" the DQ10 is not "light" if placed on their
standard 3 little foot (about 12-13cm height). DQ10 become light if is
placed on stand of 30cm (or more).....

Hello, i am french (near Paris) and i am sorry for my bad english... but i will tried to make my best...

I was looking information on internet about the B&W DM6 and i found your website with the list of recommended products where was the B&W DM6... I know this speakers because a friend of mine have them in London, and each time i am visiting himself i was amazed at how good this speakers sound... even compaire to my speakers that are JBL 4311, Acoustic Energy 109 and Klipch Cornwall I.

The DM6 seamed to sound just perfect to my ears!! Beatifull base, marvellus mids, airy, transparent and full!! (his amplifier is an HK PM635i / 2X40W)

I am writting to you because you experienced this speakers and the Dahlquist DQ-10, JBL 4311, Quad ESL 63, Magneplanar... Four speakers that i am very interested for having especialy the B&W DM6.

Do you have any recomendation? do you prefer the Dahlquist DQ-10? you said about them that they are one of the best multi-way floor standing speaker... are they beter than the B&W DM6? do you know  a better multi-way speaker that is not on this list (in a moderate price 500€ =>2000€)

Sorry for all this questions, but before buying the B&W DM6 i wanted to make sure not doing any mistake!

I thank you in advance, and hope yould help me...

Have a good day!

Fred,

Hello
The B&W DM6 first series (with midrange all yellow) is a great speaker at the same level of DQ10.
Better of this I know only the Grundig professional series loudpeakers (box2500a,box1500a,box850a), You can read my website...
Regards
Massimo

-----------

Hello Massimo and thank you very much for responding!...

I feal more confortable about the B&W DM6, also, i never though that this GRUNDING speakers were that good... i will take a look on them.

Ehm "Grundig" and not "Grunding"....

Two last questions:

1/ I was VERY impressed about DM6 "base", (quick, low and clean) is the Dahlquist DQ-10 as good?

Yes, very similar quality.

2/ I alwas wanted to have some JBL 4333 or JBL 4343... what kind of sound it is compare to B&W DM6 and GRUNDING box2500a,box1500a,box850?

Bass reflex supply a different kind of sound in middle-bass frequency : more empty

Thank you so much for helping me...

I don't know the Oehlbach cables, you can send

I can supply a little (good) Schweiger (0,75mmq) for
small distances to speakers (not more of 3mt) or a Hama/Thender
(trasparent cable similar to vivanco) of 1,5mmq or 2,5mmq.
For place
point-line connector is very difficult to use the 2,5mmq (very little
space into connector) by the way I advice the 0,75mmq or the 1,5mmq.

Yes but is very dependent to room dimensions.

Not modify but all check for

The solution MA50+xv7500 or integrated MA10 have the advantage of more linearity due to absence of tone control. You can see the "technical test" on my website:

No advantage in CCI implementation (same level).

Dear Pawel
The difference between CCI cd player and CCI turntable is very dependent to type of recording: a digital master is more probability better on cd player, an analog master is more probability better on turntable.
If your cd7550 is in good conditions there is only a little difference with cd960LT. However the cd960 has a remote control while the cd7550 not....

Hello James
1) T30 is a very good full CCI tuner.
2) T9000 is not a CCI tuner (sound is not so good). The Grundig best tuner is the T7500
3) The cover (grill) of box350 (first type) is maintained with stucco: you must make lever in an angle with a little screwdriver in order to detach the grill from the stucco.

Hello Sebastian
I know the old box 80 , good boxes with old hot sound and cone tweeters but if you like the better trasparent sound I advice more the Grundig products presents on my website.
However the trasparent sound box need of trasparent sistem CCI : box more trasparent evidence more defects to mount.

Hi Massimo..

I'm so glad you respond my question..
My correct name is Jioe.
Yes, we both very please with the CCI sound result. I bet your LT amp doing better!

In this note, I attached some photos of my 2nd V35. The first one using siemen was borrowed, so I can't take the photo yet.
I hope the files are not too large. In the photo, you can see ROE 10000mfd is some kind of rusty.. Is it risky? One of 4 power transistor had different look. Is it no problem also?

I have Philips 303 also. Some information on internet says that it definitely the same like CD7500. Is it true? But unfortunately, it generate some noise, just like a cellphone interference. It happens just for few minuttes when device turn on. 

Thanks for your concern..

Hello Artur,
I am happy you appreciate my suggestions. I hope you'll complete your Grundig system soon and let me know your comments.

I had some mail exchange with Greagaudio but I do not know him and there isn't any direct relationship between his work and mine.
I advice to NOT MODIFY all Grundig CCI products.....

Modern hifi producers spend a lot of money for marketing and design; a lot less money for research. In fact, some "classic" products (BBC LS3/5a, ESL63, Dahlquist DQ10, Leak amplifiers) sound far better than modern products, as you can listen in direct comparisons.

Grundig of 70/80ies is another story due to some very advanced technical solutions.

Hi Dragan,

I am happy you have found a CD7550 in very good conditions.
It is
very rare. For interconnect cable you can look for SCHWAIGER TFS
2052
or old Grundig.

R7200 and V7150 are quite similar in sound quality. If you find in good conditions and low price, you can choose one of them waiting for one of the suggested.

Dear Michael
To never believe (forums,reviews, etc...) but always to listen with the own ear!
I advice to sell dq30 ( the worse Dahlquist that I have listened) and to render non-mirror one of your DQ10. Then you can find a Grundig CCI amplifier and a Grundig CCI cd player (see my website) and live happy!

you don't reconnect the B&W... :-)

Of Grundig productions I can supply only the turntables PS1010/1020 and the preamplifier XV7500 both checked for CCI implementation.
I can supply also interconnected cables enough equivalent to Grundig cables.

Hi,

congratulations on your purchase. The SL1000 are very fine speakers

and they should be matched with others Grundig components.

To connect the speakers to your amplifier, you have to buy a couple

of 2 pin DIN plugs and terminate your cables.

>Robert

Dear Robert
Aktiv20 LT mod. are very similar to box850a + MA50 (or MA10) but are very differents to SL1000
speakers! The SL1000 is a 2 way that needed a small room (not more of 15mq) for supplies a good result to low frequency and much care to installation. Moreover is needed a listen point near to rear wall
(wall-ear distance about 40cm). In this conditons the SL1000 supplies a sound more free of 3 way speakers and it maintains the middle frequency of 3 ways.

Dear Massimo,

with interest I read your website from time to time and I enjoy it each time.

I do not own any of your specially recommended equipment but are interested if you had the opportunity to listen to a Grundig device I do own personally and which does not appear on your site: It is the Grundig Preceiver X55a (in combination with 2 pairs of Aktiv Box 30 and 40), a device from 1979 and back then constructed for combination with Aktiv Box 20/30/40 or 50. Though not especially “neutral” I think the sound is very enjoyable and conveys a lot of musicality.

As the X55a is a class A device I think it was the basis for the construction of the later XV7500 (and SXV6000). Did you listen to X55a and Aktivbox 40 combination and have an opinion on it compared to later Grundig equipment recommended by you (XV7500)?

Kind regards, Michael

Dear Michael

Yes, I have listened to the x55a with great satisfaction and it’s a full CCI apparatus as xv7500.

The differences between x55a and xv7500 are due to presence of tuner on x55a and to tones control excludible on xv7500.

Tones control excludible is an advantage for xv7500, the tuner (on x55a) causes an impression of more harmonic sound but it’s only due to more insensibility to not correct installation CCI.

See link “installation” on my website.

With aktiv box standard (not CCI updated) the x55a supplies a great result but less deep and less delicate than the combination xv7500 + aktiv box LT mod.(CCI updated).

Dear Robert

The two solutions could get the same performance if you can place the MA10 between the boxes (for reduce the length of power cables) and place on rigid surface the xv7500.
The solution MA10 without phono has a disadvantage: does not allow you to use the turntable... :-)

Yes, but have you a turntable ? If yes I advice XV7500+MA50, if no I advice integrated MA10 ( without phono)

>By the way, what's different between MA10 with v7000/v1700/v35(I have one
>for Box350)

The CCI implementation is the same of Grundig V1700 (optimized for soft surface).The sound differences are due to tone controls not deactivable on Grundig integrated .
MA10 supplies a little more deep image and little more "thickness" of musical istruments.

Hello Ritchie,

thanks for your e-mail. The 5000 series is not so good as the best

Grundig (full CCI) amplifiers (V7000, V1700, V20, V30, V35).

Dear Massimo,

Last week I followed your instruction to place cd94mod LT+ v7000 + 850a, and I got fantastic result! I am thinking my xv7500. I don't think that I could have enough money to buy MA50 or DSL speakers. I am wondering whether the xv7500 + Aktiv 30 LT-mod is better than v7000+850a or not?

Best Regards,

Robert

Dear Robert,

if you want to compare active speakers to the passive, you should compare the Aktiv 20 to the 850a and Aktiv 30 to the 1500a as they have the same woofer size.

Listening to the Aktiv series with LT modification, the result is a bit more dynamic and the definition higher. But the sonic result is really similar. The Aktiv series must be used on stand (36cm height) and well placed on 4 points.

Dear Cinderella (what a strange name...),

Grundig Super Hifi Box 450 is a very good choice, just a bit worse

Dear Massimo,

Sorry for the late reply as I just came back from a seminar conference
overseas.

I have found the DSL sounding smoother and more coherent with longer
break-in period. The cushion experiment really improves the solidity of
the whole sound landscape. Image staging becomes somehow more precise
with improved tunefulness (listening with feeling). Now I wonder how
you could come up with such an ingenious idea of the cushion treatment
:-)

When you are not too busy, please tell me some other nice recordings to
enjoy LT System even more. The obvious sensation of having a complete
Grundig/LT system around happens to be the irresistible factor that we
want to listen to music most of the time. It's becoming harder to
switch off the system, is this also happening to other LT members???
:-)

Best regards,

Handoko

Dear Handoko,

The idea of the cushion treatment is related to the reflexions of the
internal side of loudspeaker cabinet. These cause irregularities (peaks and dips are reinforced) in the frequency
response. The 1/3 distance of the cushion improves linearity. In fact, the distance of the reflection is now different for both sides and peak and dips are far less severe.
The cushion works well with symmetrical speakers (like DSL) but does not apply to asymmetrical speakers (like
3way grundig speakers: mid and tweeter are not specular) as they already have different
distances in emission centers.

Best Regards
Massimo

good as older Box400 or Box500. But, as you do not intend to use them
in a Grundig chain, you are free to choose them if the price is low.

In fact, the best combination for older Grundig speakers is the full
Grundig chain (V7000, V1700, CD7550, CD7500) or LT chain.

Best regards
Massimo
 

Dear Massimo,

Thank you very much for your answer.

So I would better look for older models.

I have a few questions, because there are a lot of Box's models and I do

not know yet the hierarchy between them.

The best series is HiFi Box 300/400/500 & 350 (or it is called

Compact-Box 350?)?

Is the series Super HiFi x50 almost as good as the older ones? What

about speakers from this series, but called "Professional" - are they

better than the normal ones?

I also found Compact-Box series (e.g. 350a, 353) and HiFi-Box xx3

Compact (e.g. 403,313) - how are they?

For my room (9m^2, speakers will be on a bookshelf), what models should

I look for: from 3xx to 5xx? Or 5xx would not be appropriate (e.g. too

big)?

I understand and have respect to the fact that the Grundig chain gives

the best best results. However, nowadays I cannot change my audio

components (maybe in future when I get involved in the Grundig passion

:-) ).

Sorry for disturbing you with my boring questions.

Best regards,

Grzegorz  xxxxxxx

Dear Grzegorz,

You can choose the Grundig Box 550b or 350a or 353 or 313: this is
the best choice for your hifi chain (they are 2 ways and differs on
woofer size: 3xx = 11cm dia; 5xx = 16cm dia). The choice is related
to the acoustic of your room: if the bass reinforcement of your room
is excessive, you should choice smaller models.

Please, do not buy Box 300/350/400/500 or Professional series if you
do not own a full Grundig or LT chain. These loudspeakers are very
transparent and precise and they need an accurate interface. They
probably will sound unpleasant with your system.
Best Regards

Massimo

Enjoyed your website, very good.

I have just purchased a pair of vintage B&W DM6 speakers, they are in immaculate condition and are the best speakers I have ever owned, but could you tell me what the dial is for on the back please.
There seems to be a shortage of facts about the DM6 on the web.
Look forward to hearing from you.

Regards
Brian

Dear Brian
The dm6 was my first love and still remember it with affection. The dial on the back part was present only on the first series of dm6 (the better) and is the control of level of the woofer. Congratulations for your purchase!

Best Regards
Massimo
 

Dear Sir,
I was very pleased to find your website and to join grundig_LT group. We share the same opinion about GRUNDIG products from 70s and 80s.
I would like to ask you if you could give me your opinion about following products: receivers R400 and R7500, and amplifier
SV1000 (of course made by GRUNDIG).I was so lucky to get in possession also speakers 650 and 850a professional and amplifier V7000.
Sincerely yours
RAdan xxxx
 

Dear Radan
The SV1000, R7500 and R400 are not totally CCI implemented (about 90-95%) only v20,v30,v35,v7000,v1700 are full (100%) CCI implementation.
However all the Grundig products of years 75-86 are development with CCI implementation and the results.....
you can listen it :-)
Best Regards
Massimo

Dear Massimo,
Thank you for your answer.Since I am almost a audio beginner (despite the
fact that I am an electrical engineer) would you please help me to find a
link with some technical details about CCI implementation.
Best regards
RAdan

Dear Radan
The acronym CCI (circuit chassis interface) has been from
me invented in order to identify the fruit of 20 years of search on a
particular phenomenon. I have seen such type of implementation applied
before only on the Grundig apparatuses of such period. Sorry but I am
not available to supply of explanations but only demonstrations of CCI.

Best Regards
Massimo

Dear Massimo,

The DSL shipment along with Grundig CD7500, HiFi Box 300 and other bits arrived safely last Friday while I was on duty out of town. Thank God everything arrived in good shape!

I auditioned the DSL for the first time for almost 2 hours today when my sister came over to listen to some music thru my complete Grundig/LT system (Philips CD960LT, XV7500, MA50 & DSL). To put it shortly we praise the system’s ability to give us a pleasant access to musical listening journey. That may sound simple but certainly not an easy task to carry by any Hi-End systems. Most of them completely fail to achieve it.

However, I’m not sure if my audiophile fellows would agree with my assessment since the DSL surprisingly produces similar open window like the Quad ESL63 from a dynamic speaker design. But it does a better job than the ESL63 in portraying rich details and musical expression. The Quad may sound smoother, warmer and thicker which some may prefer to the DSL.

Even at this stage (not break-in yet) the DSL already sounds very impressive; music flows beautifully and very transparent (no congestion) with rich of musical expression. And I don’t hesitate to say even my favourite ESL63 cannot provide musical details & feelings like the DSL. Music sounds colder and a bit more dull/lifeless thru the Quad despite its unique charms! Does anyone remember Ella Fitzgerald singing a famous Duke Ellington’s composition ‘It don’t mean a thing if it ain’t got that swing’???

Sorry Quad ESL/ESL63 lovers but I must admit as a proud owner of both models that the DSL gives you more swing to Count Basie, more heart touching to Billie Holiday, more soul to Wilson Pickett and more boogie to Deep Purple than the the Quads. Got the message now?

As a music enthusiastist, I myself try to avoid to be called an audiophile since I have met so many

audiophiles who called themselves audio guru/experts promoting perfect sound but in reality they don’t know what aspects should be justified when listening to music.Oh what a pathetique!

A number of so-called audiophiles prefer to analyse the cosmetic aspects of sounds instead of the basic rendition of musical finesse and expression. Maybe as most of them are musically deaf or blind (illiterate) and not aware of what crucial aspects we should look for when listening to music (NOT sound!). In my humble opinion, harmonics and nuance in music should be one of the very underlying factors when appreciating Hi-End system performance instead of the mambo jumble audiophile terminologies which are irrelevant to the art of music itself. Therefore I don’t believe in hifi/audio magazine anymore but rather take them as bedtime stories to help one fall asleep quickly. Agree?

To me perfect sound means nothing if it does not convey the musical message positively. It’s as simply as that. My relatively short listening experience with a complete Grundig/LT system has reminded me how many Hi End systems I have heard missed to reproduce the true meaningful aspects of music which I now achieve with my LT system. Of course, it’s not perfect but music is becoming closer to the heart. Isn’t that what we are all after?

It’s a simple testimony as a token of my appreciation to the great works of Maestro Ambrosini.

Bravo Massimo!

Warmest Regards,

Handoko

Dear Handoko,

Thanks for your kind comment !

I am very happy to know you appreciate my effort to give you the best result today in musical reproduction.

I hope you have more time, in the next few days, to enjoy the system, and even to test the foam rubber cushion to use between the speakers (see DSL user manual)

Best Regards

Massimo

Dear Massimo, 

Thank you for your kind reply.

I have a friend who called me this morning after hearing the LT system yesterday; he wanted to buy my complete LT system including the Quad ESL63. He is so convinced that he really heard the best sound out of the ESL63 ever in his life. The big question for me is about a system replacement from you. Could you deliver the same equipments (XV7500, CD7500, MA-50) without having to wait too long?

Please advise.To give you more exciting news. I just came back from visiting a friend who has very expensive Venture speakers & pre (passive) / power (single ended tube-monoblocks 15W). His turntable is SME’s flagship model, 30 with SME V arm and Koetsu Jade MC cartridge. Total cost for the front-end alone is exceeding US$20,000 + a phono preamp by Ensemble (Swiss made). I brought a Grundig PS1010, VX7500 and MA-50. We keep using the same Venture speakers (using ceramic drivers) to make the comparison less complicated. The PS1010 is using a Shure V15 Type 3 to get a more refined sounding to compete against the Koetsu Jade MC ($5,000).  

The audience consists of 12 experienced audiophiles who love listening to expensive Hi-End systems but the shocking news is they all prefer the sound of the humble, cheap looking Grundig PS1010 with Shure MM cartridge than the super luxury SME Model 30/ V arm/Koetsu which costs 40 times the Grundig with the V15 Type 3. We played a few different records with various musical genre and still the winner is the ordinary looking PS1010. The listening comparison was so jaw dropping to the audience!  I personally felt with great confidence that the Grundig would win the war and that’s why I initiated the idea to arrange the comparison test against the SME without any fear. Everyone was simply astounded with the superiority of the PS1010 to be able to reproduce musical performance, ambience, details, transparancy, correct note, rhythm & pace in the recording much much better than the sluggish & dull sounding of the SME. It’s a night and day difference and the whole game was almost like a joke. We should ignore SME for being so overpriced and a big failure in turntable design. What a shameful politic among the Hi-End manufacturer! 

Bravo to you, Massimo, for your ingenious ideas to share some great information about Grundig’s best kept secrets and your valuable mission to save our financial status by preventing from buying hifi products who don’t deliver the music. A big gratitude to you! 

Best wishes,

Handoko

Dear Handoko,
thanks for your kind comments.

Just an advise: please do not replace the original cartridge of the PS1010 with the Shure V15
Type 3 or others. If the PS1010 is correctly installed, it reaches the best performance only with the
original cartridge and original shell.

I am sorry but I am very busy and I can supply a new complete system
(XV7500, CD7500, MA-50) only after Christmas week.

Best regards
Massimo

Dear Massimo,

For your information, I did not change the original cartridge on the PS1010 which you supplied. I leave

it as original to maintain a genuine performance by LT standard.

The PS1010 which was fitted with a Shure V15 Type III belongs to a friend so it is a different unit. And I am also curious if using a V15 Type IV would be even better than the Type III which already killed a $5,000 Koetsu Jade MC.

.......

Best Regards

Handoko

Dear Massimo,

Sorry I just got home from a long business trip hence the late reply to you.

Today I connected the MA-50 driving Quad ESL63 with superb results. I use a Grundig XV7500 preamp and CD7500.

Several friends came over my house to listen to the Grundigs + MA50 with the ESL63 and we all think they are the finest and most musical sounding system we have ever heard from Quad speakers!

Thank you very much for your kind help & assistance.

Best wishes,

Handoko
