Okay, thanks to many responses from everyone, I think I have come up with my new system to purchase: 2 B&W DM603 S3 Fronts 1 B&W LCR600 S3 Center 2 B&W CDS6 S3 Sides (monopole or Diapole capabilities) 2 B&W CCM65 S3 Rears Round out with a B&W ASW650 Sub I am running this with the Yamaha HTR5790. System is mainly for Hometheater, but will also be for music. Room size is 14x22. Does this sound like a good setup? I know if I spent additional $$, I could get an amp(s) etc, but do I really need one initially for this to sound good and have enough power?
