[6/30 Update: Posted new, better pics in response to a question] Phenomenal sounding amplifier at a great price. I'm the original owner and still love it. I'm selling only because I'm moving house and it is no longer feasible for me to have a separate, two-channel system.
If you're looking at this ad, you probably know the capabilities of this amplifier. I bought it on the strength of (I believe) Richard E. Greene's review in Issue 125 of the Abso!ute Sound. Here are some links to other reviews:

Quick Stats: 200 watts per channel (8 ohm load); 330 watts per channel (4 ohm load); fully-balanced but also accepts single-ended inputs.
I had wonderful results with a tube preamp going into this amp, but also found it to work well with a solid state preamp.
