[QUOTE="LAV, post: 60493, member: 1123"] Yes, the assumption of course is that chances of all channels being driven to full power at the same time = very slim. Still, larger power supplies offer more reserve power and therefore better headroom. Take a look at the power supply vs. output rating of most good quality power amps, and you'll see it is the opposite, i.e. the PSU / mains transfomer rating is quite a bit more than that of the total output of the power amp. Back to real life: A decent multichannel AVR receiver set up properly will produce enough oomph to offer a satisfying home movie experience. The compromise is made because of cost - the "Plan B" option would then be a processor / preamp driving separate power amps, but then of course your wallet needs to keep up. :) [/QUOTE]
