I need some advice here. I'm planning to upgrade my system... ML Aerius fronts, currently driven by Adcom 545II, via Yamaha RXV-1000 pre-out (I know, not ideal, but it works). My system is dual purpose 90% 2 channel audio, 10% home theater (using the Yamaha RXV-1000 to drive the B&W center and surrounds, and NHT SubTwo). Having a large (poorly ventilated) A/V cabinet, I need a COOL running amp, so I plan to go with one of the IcePower designs... looking at eAR 501 monoblocks. Henry Ho (H2O Audio), and others, also offer 2 channel IcePower based amps. I also plan to biwire the Aerius. I'm assuming that dual monoblocks, would be better than a single 2 channel amp, all other things being equal. Any other suggestions on how to maximize 2 channel sound in a (modest) home theater setup? I eventually plan to upgrade to a Fresco for center.
