First, loose the Receiver. 7.1 system is a great idea for 1 reason, it's always best to run a separate 2-channel music with a separate amp. You can always upgrade to better ones later if you don't like the sound mates with your B&W much easier with 2 then with 5 channel amp.Get a Proceed AVP, great with 2-channel music(read the reviews). Anthem amps and Sunfire amps are pretty much the same you can live with either one. As far as music goes, well, Classe amps do go well with B&W.
