buckcrazy,
The remark about the "reference level" by one our Axiom guys likely means that if you are in a really big room and you like deafening levels of playback with the M80ti, the Denon won't do it.
Be realistic. How big is the room (length, width, height). My colleague at Axiom, Jean, managed to shut down three huge monoblocks (250 watts per channel) driving M80s to levels that he obviously liked. I had to leave the room.
If your tastes lean towards loudness levels like that and you are in a big room--6,000 cu ft. and larger--then get a basic 2-channel power amp with at least 150 or 200 watts per channel to drive the M80s.
Regards,
