TRULY RARE...ONLY ONE PAIR MADE BY MASTERSOUND...52B VAIC REFERENCE MONOBLOCKS #001A / #001B

Selling my beloved Vaic 52B Reference Mono-blocks made by Master sound in Italy ! Selling due to lack of real estate in my new home and this is begrudgingly. I expected to die with these puppies as this was the end of my "audio quest" looking for that "sonic bliss " and I found it with these. These are truly rare in every sense of the word. Almost a Unicorn. They come from a smoke free environment and have been well cared for. Also, these have never been molested / messed with circuitry wise. However, they were professionally re-configured to auto-bias and for good reasons...who wants to mess around with gain / analog and a screwdriver. I can't even begin to tell how incredible these amps sound. I know in the audio world everything is so subjective but these babies sound juicy !!! I refrain from words "liquidy and organic"...c'mon ! Ok, if I had to describe how these sound , think of big piano like tones ....absolute bliss. Also, no hum from these babies cause they have been built to exceed all expectations...so if you hear a noise, your wiring in your house sucks ! Float it all. They come with X8 Mullard GZ-37 Rectifiers, four per amp and X4 Mullard 12ax7 / 12bh7 two per each amp as well as the  pièce de résistance... the most incredible power tube, the 52b Coke bottle blue Alesa Vaic tube...each amp has an original power tube. I'm not even going to try and guess how many hours are left or I've used them for but I'm confident short of lightning hitting your house ( invest in a $100 surge protector wired directly into electrical panel ) these will sing as long as you live. Such as the nature of tubes there are no guarantees, as anyone at this level understands. Hence, the auot-bias allows you to run a few different configurations of power tubes. Also, there is approximately $4500 invested in tubes for the amps.

It should be known that these amps are verified by Mastersound as they sent me the original brochure to substantiate their authenticity as well as an email from the owner of Mastersound / Employee indicating as follows

Ciao,

This amp was produced by my company Mastersound for  KR - VAIC VALVE in
about 70 pairs from 1995 to 1998.
It has remained this brochure printed at the time. If you need to change
the tubes can replace the VV52B with the  52B Emission Lab, produced in
the Czech Republic, they are also excellent valves.
I am very pleased to have news about  the amplifier  number 1 which is
also the only one made with copper canister!
I send to you the material I found

Best regards

Lorenzo

Thx for looking. Also, would trade for Luxman / Accuphase or Onkyo Grand Integra Power Amplifier. 

Note: I'm not looking to get into any discussions about whats better etc. The above rant is all my own opinions and I do realize there's better !!!
