I did not want to get into amp choices yet but I am planning on likely 300 Watts per channel for the front three. Example ATI AT3003 (300 wpc) and if needed a AT1804 (180 wpc) for the heights and surrounds. I believe the amps in 4311 would be adequate for the heights and surrounds, just whether it would be as good as a prepro.
Edit: if I go Studio2 & Voice2 then for sure 300 wpc x 3 but if I go 205/2 & 202/2c I could also do 300 x 2 and get a five channel for the rest, say 200 wpc. Right now I want to figure the front end.
