SANSUI AU 111
« on: Jul 30, 2014 at 12:45 AM »
Starting this thread to know other members who currently owns the legendary Sansui AU 111 tube amplifier.

Sharing my rare Sansui AU 111 tube amp fully restored to immaculate condition. Very nice sounding for a 48 year old model 6L6 tube amplifier.

AU 111 have this surprisingly deep bottom end with soul to music passages, making it very revealing to any genre being played whereas AU 9500 has the balance and transparency that you can get from most expensive amplifiers. Warm and exude with amazing detail to musical passages.

Well both AU 111 and AU 9500 are highly regarded by old and new audio enthusiast.

There was one review that says "AU 111 is considered to be one of those amplifier that you need to have if you're a serious audio collector"

Matagal ko na alam na AU 111 was considered as sansui's tube amplifier legend. Sana swertihin din ako to
have one.

my 12EN6 pp amp is very similar to the au-111 circuit which i favor a lot in my builds..

the au9500 otoh is a solid state amp...

hold on to those tubes, the peanut tubes are almost indestructible,
the 6L6GC's are ussually the first ones to go, but the fact that they are
still alive is a testament to japanese quality...

Got this article about Sansui AU 111:

AU-111 was the ultimate tube amp Sansui ever produced.  This was the Sansuiā€™s technical submit of its root transformer production.  Also, in circuit design, Sansui adopted the latest of many years of tube technology.  As the result, sonically, I don't think there is not much room to improve.

Sansui has been a company that improves its products step by step.  The early Sansui transistor amps, such as AU-999, AU-9500, AU-9900, AU-919, and AU-D11 all sounded like trying to be like tube amps, and never got there.  Sansui stated to change that from AU-D11II, AU-G99X, and AU-X701(this was AU-Alpha607 in Japan (1988)).  The high frequency of AU-X701 is so sensitive that Sansui has succeed to go to the root of tube technology; however, they were definitely weak in low compared with tube amps this is nothing more than comparison, I still like the sound of AU-G99X and AU-X701 much better compared with today's expensive transistor amps.

By knowing this Sansui tradition, the astonishing resemblance in sound between 907MR and AU-111 tells me that Sansui might have been designing its amps to reach the ultimate sonic submit they have already reached thirty years ago.  Even, they might have been using AU-111 as a reference amp for their goal. I can ask those questions to those Japanese engineers whom Mr. Motoki has introduced to me.

This suspicion also coincides with what Sansui did.  As I said, Sansui has been a company that always tried to improve the product by one step at a time.  The last high-end integrated amp Sansui ever produced was AU-111G in 2000.  This was AU-111 specifically redesigned on the pre-amp section for SACD and DVD Audio use.  By considering the Sansui tradition, if AU-111G had not sounded equal or better than AU-Alpha907NRA, they would not have introduced AU-111G.  This thought process and the result of my test also tell me that Sansui finally archived its goal before it ceased to exist in high-end audio market; to produce the ultimate transistor amp that is equal to the best tube amp Sansui ever produced.

natural manufacturing progression, engineering revisions if you will...
in the course of the life cycle of any manufactured product,
revisions and modifications are natural course of events,
with newer parts and better quality ones to boost sales.
quality rules.....;)

Nice specimen of the AU-111 you got there sir. I have one too and I may need help restoring it. Can you please recommend someone who can restore it? Any help is greatly appreciated  :)

This is actually my first post. I've been a lurker for quite awhile.  So hello to the guys in this forum.

Hi sir, it's a gem for having that. If you can restore it w/ a respectable tech, this will sings great.
