What would be the 'best' Sansui amplifier for sound quality?

[czubsi]

I think my bad translator translated the word

the problem is that the Japanese model is always a bit different for their European version! All LAPT are also non-magnetic ones in total sales as SA1303, etc. For example, AU-alpha707i the equivalent of AU-X901 have a lot of differences! Look at the type of the disc in both ...AU-X911DG was a mutant version of the AU-alpha777 and alpha999 AU-...alpha907 in the Japanese version also differs from the European and sometimes significantly - to the detriment of export version

All LAPT (including commercial versions such as SA1303) were non-magnetic! From model Lextra copper plate used in transistors and that the AU-X711've never seen! AU-X711 is the equivalent of AU-alpha607extra obviously a bit depleted ..

I think my bad translator translated the word

So let me sum it up for you. Correct me if I am wrong.
My understanding is that in your opinion the absolute best is Sansui AU-07 (Anniversary), made in 1996
and probably AU-alpha907Limited , made in 1994.
Of course these are very small production models, nearly impossible to find.
Best of full production models then are early to mid nineties alphas: L Extra, DR, KX, XR.

What do you say about AU-alpha607NRA II from 1999 ? Last production Sansui.
There is one on ebay right now.

 

[czubsi]

no! In my statement of AU-07 is relatively far! My ranking:

1) B2302L/C2302L
2) AU-alpha 907LIMITED
3) B2105MOS VINTAGE
4) AU-alpha 907MR / AU-111G
5) AU-alpha 907NRA
6) B2103MOS VINTAGE
7) AU-alpha 907XR / AU-X1111MOS Vintage (last version - TAMURA !)
8) AU-07
9) AU-alpha 907DR/KX and AU-X911DG (my mod !)
10) B2301/C2301
11) AU-X1111MOS Vintage / B2102 MOS Vintage
12) AU-alpha 907i MOS Limited
13) AU-alpha 907 L extra
14) AU-alpha 907i
15) AU-alpha 907
16) B2102/C2102
17) AU-X901

Best Sansui Amplifier

Thanks for the postings czubsi

As an owner of a Sansui AU-911 DG I was wondering if you can list or give me a link to your mods. I'm having a hard time Googling them because of the language differences. I think that the 911 DG has excellent sound even without the mods and would be interested in improving it. Also, what do you think of the DAC in the 911 DG and are the mods also appropriate for the Japanese versions of this amp and the ones higher up in this series?

Thanks. Marc

No NRA II on the list ? Any reason for that or you just dont know it ?

I have not heard of the site, but judging it's only alpha 607 ... Each 707 will be better Qualitatively the level of the list of 13) / 14)

 

[Hyperion]

I seem to have collected 4 examples from 18+ according to the list - must do better

Luckily mine were not on the list either - no temptation to sell them for huge profit! In 6 months this thread has been red by everybody and those on the list have their prices skyrocket and they will show keywords like "the best" and "rare" in their e-pay -ads

Dobra robota Czubsi :thmbsp:

 

[czubsi]

This list of my feelings! I listened to them all and most did not even see the eyes - it is worth remembering ...

Prices high and valuable Sansui models at the moment and so are attractive compared to today's high-end!

I do not know if you know but the price ratio of the components used on some models Sansui reached 1/3 the price!! Find the other such equipment! approx. 80% of the alpha 907 is limited components made ​​to order

P.s.
Dzięki Hyperion !

 

[ToniCH]

This list of my feelings! I listened to them all ...

Yes, I understand completely. I've never heard even one on your list. So, don't worry I am just joking about the prices and such. I am happy with mine, maybe I don't even want to hear the ones on your list so I wont feel bad about my Sansuis.

 

[czubsi]

where are you from? From Sweden? U you have sold some 907 DR (from what I know of 6 pieces ... Nothing is with us-there was even a representative Sansui ...

AU-717 is cool! But this is completely different shelf quality. Listen once such 707DR will have what you have now so that a few times - in every way

No, from Finland. And I am listening to my AU-9900A right now, very happy with it

 

[Pepa]

bluesky you have a lot of reasons. The truth is, however, so that the old models of strong coloring and are not as fast as alpha - the difference is really big!....
:yes:

I always thought that AU-X1 was (is) the fastest Sansui amp :scratch2:

Tony,there is nothing wrong with your amp.. it is a great amp... just paired it with good pair of speakers and that's it.
Believe me,I could live easily with mine (9900A/11000A...paired with Harbeth SHL-5) for good.

@czubsi
I quickly looked at the Polish forum (using a translator, of course) and if I'm right,you guys over there have couple of 907DR,2 or 3 907MR (not to mention the smaller models). Also, if I understand correctly, you're one of the most experienced (together with Jan), but I did not see that any of the forum members have 907NRA,or A07,or 1111mv, or C/B 2301...am I right?

AU-X1 was the fastest! Anyway, it caused a lot of problems with it - easy to burn ... Later designs were already fixed bugs.

Pepa almost everything is correct one friend (named młynas) announced that it has 907NRAThere are two AU-X1111 MOS Vintage (w / g my knowledge 907 MR - 2 , 907 DR -3 , 907i - 1, 907 alpha -1 ... There are some 707 DR, 707XR and a pair of power amplifiers. In days to come 707 NRA. You need to take pnp. of note that many owners do not write on the forum - I know many that have and do not write ... 907NRA I had from a friend in Germany for a month. I bought because I thought 907MR, the NRA is better than that w / g me playing too hard and forcefully. DR 907 escaped me because I bought the AU-X1111MOS Vintage in Germany

listened to a number of models or comparing borrowed from friends in Holland and Germany. I try to have the widest possible knowledge of the Sansui to be reliable! Jan is my friend - it got infected Sansui

alpha series so far I did not have to deal with 907XR me something because I still falls ..

 

[Qsiris]

I saw the list and its completely dominated by so called 'alphas'.
I have a friend in Russia and he confirmed the same preference.
Must be European taste for elegance and finesse.

Here in USA men want their amps to project strength and power.
"Built like a tank with powerful sound " is what real alpha male wants.
That's the American way ! (Hard admission from someone who owns and enjoys an "alpha" :sigh

Amps in champagne colors ? Leave it for European girlimen .

Real men own AU-X1 , the best of Sansui !

Ha,ha...:lmao:

Qsiris,consider the weight of the alpha amplifiers...over 30 kilos :scratch2:

Almost everything you said is common knowledge

B2301/2302 is a real American stuff :thmbsp:

 

[bluesky]

bluesky you have a lot of reasons. The truth is, however, so that the old models of strong coloring and are not as fast as alpha - the difference is really big!. The rule is so that everyone likes what is But I have what I like!

bluesky

The truth is that the nearest neutral tone pattern is AU-alpha 907DR! Later models such as the XR and MR twist the lamp! Everyone has different tastes but the pattern is the one! You have to hear the Alpha 907DR questioned XR and all will answer!

bluesky listen AU111G 907MR and if they recognize the band put in front of the whiskey!

:yes:

I totally agree. :yes:

Thanks Czubsi and all for your in depth write-ups and explinations. Most appreciated!

Czubsi good writing... You thinking as well as a one member of the Croatian and also of an Audiokarma forum ..... We know that Sansui has manufactured the highest quality equipment, with the top parts from 1990 until its end of 2001. I'm referring to the Alpha 907 DR, MR ....... some Vintage line . But it is not necessarily a guarantee that it will be the best sound. And before this period Sansui was making excellent devices....
If we ignore the measurement devices and other technicalities ....
I think the highest problem is in our ears, heads and especially in our wallet

I totally agree too. I think for most folks, expecially the wallet part. We all know which amps are the great ones, it's just getting it shipped from Japan.

For me I'm really happy and content with the amp I have, so guess I'm lucky.

Would I like an AU-X1111 Vintage? Sure. I'll end up with one 'someday'. Would I like any of a 'few specific' Alphas. Sure.

Is there anything wrong with the older Sansui's? Not really. They sound great!! Maybe they are not of the Alphas quality in design but they sure do sound really good.

Other than specs, for me, it's personally finding an amplifier that you enjoy and are happy and content with. There's always better, there's always worse.

I'd love to have an AU-X1111 Mos Vintage. Someday, maybe.

You really need to change your default response to the MOS Sansui's saying "no spare MOS chip any more". Its sending the wrong message to people potentially interested in these amplifiers.
Firstly they are MOSFET devices (Field Effect Transistors), they are not Chips.. They are also far far more robust than almost any TO-3/TO-3P bipolar transistor and would need something extraordinary or someone doing something incredibly stupid to take them out.
Secondly, although they are no longer manufactured they can be found, I service Perreaux MOSFET amplifiers (1980's models), I have NEVER seen one with blown MOSFETS, even so if they have, I have three sources where I can obtain the devices.....there are plenty of them around.

What I am saying is although some parts are no longer manufactured, it does not mean you cannot get them.

I would take a MOSFET Sansui any day, there i

s nothing to worry about with parts failing and being unobtainable, because in my book theres no such thing as unobtainable....:thmbsp:

Yes, they are not chips. Plenty around, got it! But for us regular folks they may be hard to find. I know you could get them. Somehow. Might have to wait awhile, but as with any rare part...it can be found...someday. Easier if your in the business, like you are.

I've had it with rare parts. I try to stay away from that. I've been looking for a used Sansui W-112 used woofer now for 3 years!!! But you have 3 connections for the MOSFETs so that's really cool!

Side note: Seeing your in the 'business', if you ever find a W-112 used woofer for Sansui's AS-300 speakers...please PM me! I can't find one in any country. (short of buying another complete pair of AS-300 speakers just for spare parts). Thanks!!

 

[leesonic]

I'd go with an AU-D5 or A-80, but only because I own both of them.

Lee.

 

[bluesky]

That's OK - for the record I have AU-717, AU-919, AU-D11 II, AU-X701.

:thmbsp:

How do you like your X701 'as compared to' your: AU-717, AU-919, and AU-D11 II ? :thmbsp:

Used to have an AU-717 and I really loved it. Still have the TU-717.
