I thought I posted this the other day, but it didn't work for some reason:
Wyred4Sound Mini MC 5x220 Class D amp is $2,000 (slightly over your budget but a hell of an amp). I happen to like Class D amps - especially for HT. They run cool and have lots of power and control. The W4S amp gets great reviews. I haven't listened to it, but I have a Bel Canto that is similar in design and reviews.
Another great option is an NAD Masters M25 amp on A'gon used for $1,799. 7x160 (and NAD watts are typically underrated). Retails for $3500.
