my cousin powers his M80s with an Onkyo TX807 wich pushes 130W per channel.. Sounds very, very good, even at high levels and I should know because we play our instruments (Bass and Drums) along with the stereo.. so it has to be LOUD for us to hear the music over the instrument amps..I have a 200W Traynor Tube Head with a cabinet that has 1 X 15" + 2 X 10" + tweeter. Trust me, my bass amp can play considerably louder than the stereo..but we don't over do it otherwise we can't hear the song..typicaly we run the Onkyo at around -4db when we jam and my bass amp volume is at about 3(out of 10)
At normal to higher than normal volume levels for music listening, that 130W is plenty .. I don't hear or feel that he's missing dynamic headroom.
