Well lets see, my 3808 has no issues driving my m80's, vp150, 4 Qs8's in a 30ft x 32ft x 9ft room. The EP800 has its own amp onboard and doesn't use the Denon.

The Denon is 130watts per channel

The m80's and 180 play at 95dB "in room" only using 1 watt if you look at the specs, so that should answer your questions.
