Rick, I saw your post # 7. I guess I should have expanded on what I wrote a little. For those who have compared the M22 to floorstanders in larger rooms, many have found them 'thin' in a larger space.
The RXV-2700 may or may not manage with the M80s. Some Yamahas work fine, some don't. The M80 is also a very sensitive speaker so they don't draw a lot of power, just more current and its that higher current draw that causes issues with some receivers.
