Aren't you ignoring differences in efficency? Not trying to split hairs too much, but basing a purchase decision like this off of just one number is a little narrow-minded imho.
I think I've heard those Onkyos run hot (I thought I read it around here), and if I recall correctly, the sentiment is that the Pios don't pump out as much heat. If the onkyo is generating 30% more heat for example (just throwing that out here), they could be much closer in power output than you assume...
I'm not favoring one over the other (I may buy either, or a denon), but this assessment seemed out of place. Feel free to correct me if i'm wrong, anyone.
Edit: Okay, so this is an idea
of what we're comparing...by no means apples to apples, but hopefully close enough to spark some thought...Pioneer Elite VSX-84TXH
(Just using the 84 since the 94 page isn't up...I assume it's going to be very similar)
Surround Power: 140 Watts x 7 (20Hz 20kHz, 8 ohms, .09% THD )
Stereo Power: 140 Watts x 2 (20Hz 20kHz, 8 ohms, .09% THD )http://www.pioneerelectronics.com/pn...tailsComponentOnkyo
130 W + 130 W (8 ohms, 20 Hz-20 kHz, 0.05%, 2 channels driven, FTC)
150 W + 150 W (8 ohms, 1 kHz, 0.7%, 2 channels driven, FTC)
160 W + 160 W (6 ohms, 1 kHz, 0.1%, 2 channels driven, FTC)http://www.onkyousa.com/model.cfm?m=...class=Receiver
I don't see a rating for all channels driven.
Food for thought - measurements on an 82txshttp://www.audioholics.com/reviews/r...ments-analysis
Check out the "Amplifier Efficiency" section in this Pio audioholics link:1CH, 333 watts consumption, 166 watts outoput @ 8 ohms, 50 % efficient
The onkyo lists something called "dynamic power" and shows: 150 W (8 ohms, 1 ch)
which *may* be similar (depending on several factors, of course)
I can't draw any conclusions here, but I hope I made my point that this is a muddy discussion...
