which yamaha, which pioneer
What speakers?
Generally, Denon, Yamaha, Pioneer basically comes down to features, and some sound difference
Rotel, I have no experience with it, would love to try it though, and its basically more respectable with power and handling 4 ohm loads like the m80's. Supposed to have a nice clear brighter sound.
If you are driving anything less then m80's, any of the rest will do. But, that being said, the 3805/3806, and Yamaha 4600 will handle the 80's just fine as well. See, not a very straight forward answer. Even some of the pioneers could handle the m80's in the right room.
Room size? Music taste? How "loud"?
