I don't see what is so hard to understand.
May be mtrycrafts, or others can find a better way to explain, I tried, didn't work!
On the other hand, I know for e.g., the 3805 has the following data available:
Rated by Denon(not all channel driven) - 120X7
Tests by S&V output at clipping (1KHz)
1 channel into 8 ohms - 151
2 channels into 8 ohms - 139
5 channels into 8 ohms - 107
7 channels into 8 ohms - 93
H&T tests (Crashguy posted the link)
For 2 channes:
Into 4 ohms, the amplifier reaches 0.1% distortion at 218.4 watts and 1% distortion at 243.0 watts.
Based on these data, I believe the 3805, and other similarly priced Yamaha, Pioneer, HK models (but it does not mean HK gives less, or more, as Fife asked) should have no problem putting out 100 to 120W to the fronts, and surround speakers under all but perhaps the really rare (if exist at all, in some audio/video DVDs) occasions.
I am not sure if Fife questions have been answered.
