I've been using a Denon AVR 981/2311 for about 4 years in my HT setup. It is advertised at 105W X 7 channels - 735W Total.

I found an article about this unit a while ago. HT Labs measured it as follows:

Five channels driven continuously into 8-ohm loads:
0.1% distortion at 83.3 watts
1% distortion at 91.5 watts

Seven channels driven continuously into 8-ohm loads:
0.1% distortion at 66.3 watts
1% distortion at 74.7 watts

I run most movies at -15 to -10 DB Level & music up to 90 DB SPL in a medium size room. This unit has performed flawlessly & has never clipped nor run out of breath as far as I can tell. Only mildly warm on the top cover. Powered subs of course do the heavy lifting of the lower end that takes the strain off of the AVR. I can only conclude that there is plenty of power available for my usage.

My 5.1(.2?) HT System - M22v4s, VP160v3, QS8v4s & 2XEP800v3s.

Decent AVRs are the best bang for the buck IMO...
