I guess I also need to know what is a good amount of power to go with for these Stage 4 Pis...since they are 8 ohms I wont be getting the most out of whatever amp I go with.My USA 900 put out 270 @ 8ohms and 450 @ 4ohms so quite a difference..although I suppose 8ohms is alot less taxing and will
probably result in better SQ with cheaper amps.
