Check out the B&K line - they make some 5 channel amps as well as 7 channel. Very clean, solidly built in the USA and available used - not quite the wattage you are looking for, but in real world terms they are better then most. Plus includes full function remote and solid front end.
Advice on upgrading HT system with 5ch power amp
I'm about to upgrade my HT system with a 5 ch power amp, I've got an Atlantic Technology 374 speaker system, a Sony STR 30ES I want to replace with separates a piece at a time and can spend $1,000-1,500, looking for 150-200W per channel. I live in the boonies and have no way to audition equipment so will need all the advice I can get. Any thoughts?
