For the money, I would seriously consider a used Classe CA-100. You can find this outstanding amp selling typically for around $550 - $700. In fact there are a few up on Audiogon for sale right now. They are available in black or silver.
I owned a CA-100 at the same time I owned a heavy Adcom 5-channel amp. The Adcom sounded compressed and thin compared to the Classe. In fairness, this was a multi-channel Adcom intended for home theater vs the 2-channel Classe. I've owned a number of Classe amps over the years (DR10, 10, CA-100, CA-200, CA-300) and they never disappoint. And for the money, you'd be hard pressed to find better, IMHO.
