Hi guys . need help please. planing to buy a bw 603's for main, bw lcr600 for center and bw 601 for sorounds for my home theater. but no idea which would be the best a/v receiver to go with this. can someone give me a good one. the speakers are all 100 w plus so i am not sure if a denon/pioneer or yamaha 75w or even a 90w will work fine. also if someone can advice what kind of sub should i get to match the speakers and amps. thanks a lot guys
