I had seen other threads specifically about this combination and they mostly seemed to agree that it would work. One guy had even contacted Onkyo I believe. My room is 13*30*11.5. It is a open living room / kitchen. The AV stuff is at one end and the listening position is ~10 feet away. I'd like to play it loud but it is an apartment so I can't... I want a great system now, but more than anything I'm looking for really good bones for a proper theater in a couple years.

What is the verdict on the 805/m80 combo?
