I have been running one of their cheapest amps, the LPA-1, for almost a year powering all of my Axioms. It has been on and powering my system for at least 3-4 hours every day (watching TV or background music while I cook, etc). Bi-amped M80's, VP150 center, and M22 as surrounds, using all 7 channels of the amp. My Pioneer Elite receiver couldn't handle 4-ohm speakers (lots of clipping and distortion at anything above 'pleasantly-loud').
Absolutely love the amp. I had one minor problem with one of the status LED's flickering a bit, but a gentle tap to the amp's chassis winked it back on and it's not ever done it again. I've never had any trouble with high volume levels either, whether 2-channel audio or 5.1 TV & movies. It can push my setup to at least 'dangerous' volume levels (100+db) with no apparent strain (distortion, clipping, shutdown, etc). Way too loud to actually enjoy, anyway. If aliens stole the amp I wouldn't hesitate to buy another one.
Fantastic value for $500, IMHO.
