Audio Research Anniversary Edition Reference Preamplifier

This is a very rare Audio Research 40th Anniversary Edition reference preamp. An outstanding preamplifier well reviewed by Jonathan Valin in The Absolute Sound article. 
The reputation of this preamplifier is much stronger than what I could write here so I'm not going to list all the features, I just wanna say it sounds amazing.

Both chassis are aesthetically and functionally in mint condition, like new.
