IMO, most Denon and Marantz AVRs can outperform your NAD percentagewise with all channels driven. Perhaps, but if so why don't they publish it while NAD is honest about it? (It's actually tested to be 66.3 watts @ 0.1% THD and 7 channels driven, and 77.8 watts @ 1% THD.) I've never run my 5.1.2 system off it at more than -20db, and believe me I can't do that for very long before I bow out and turn it down.
