Straight from the Denon website:

"• 7 Channels equal power amplifier section • 90 watts per channel (8 ohms, 20 Hz-20 kHz, <.08%THD) • 125 watts per channel (6 ohms, 1 kHz, <.7%THD)"

That would imply to me that you should get 90 full bandwith rated watts at any given time on all seven channels if need be. Now the FTC may only require two channels and it may be legal, yada, yada, yada. In MY book, I like the way NAD, HK, Rotel, etc. rank their power ratings. Whether or not Denon and other manufacturers are "technically" lying to me is not the point. The point is I feel as though they are lying to me. I still respect Denon products and the like, but I just appreciate NAD and HK's brutal honesty. I also understand the minute differences in decibels that 10-20 watts makes. But thats not whats important here (at least IMO).
