The BEST multi-channel amp for anywhere near that price is the EAD POWERMASTER 500. You will not find a more musical mulit-channel amp......possibly at all! this amp is UNREAL! Power-steering feature in 2 channel will direct power-on-demand to the speakers that need it most. Some say they have had upwards of 450+wpc into a single channel in stereo listening. the looks are very high-end also, much better than the other amps mentioned (IMHO). They usually are sold on audiogon for between 800-1000$$$. GOOD LUCK!!
