Sansui AU-111 vacuum tube amplifier

I agree that the Sansui AU-111 is amazing, and to me would be the piece to own.  Sansui is the one company who’s solid state gear also sounds wonderful.  I have many Sansui receivers both tube and solid state along with several integrated amps, and all of them share a sonic sweetness that you won’t hear in other brands.  I have a 9090db that seems to do everything just right.  But I still pine for an original AU-111.  

Vintage Marantz  sound,  both tube and solids state is more laid back and not sweet like Sansui, but still very very good and easier to find.

I love them both. Keep in mind anything that old will need proper service.

I have a Sansui AU-111 purchased while in the Navy on Guam in 1968. I still have it, and I don't think there is enough money to make me part with it.  I am a electronic tech, and have been servicing all types of electronic devices for more than 50 years, and have never heard a better warmer, richer, or more accurate sound than from the AU-111.  I completely restored it, replacing ALL capacitors, balanced the 6l6GC plate current, etc.  It is in immaculate condition both visually and technically, not a blemish on cabinet or interior.  Have it paired with Polk SDA II speakers.  I was also was able to obtain a pair of original A-603 MC transformers from one of the Sansui officials who had a lot of original parts  purchased from Sansui when they shut down operations.  He was living in Michigan when I located him.  I have the original manual, service manual, and a second manual I found on ebay a few years ago. 
Just thought I would add my opinion to the postings.  This is my first post.ncridgerunner
