What receiver to do you recommend to purchase with (2) Bowers and Wilkins CM-10 S2 speakers, a Bowers & Wilkins CM Centre S2- Center Speaker and 1 Bowers & Wilkins ASW-610XP 500 Watt Digital Subwoofer, and 4 CWM-663 Ceiling Speakers?
B&W lists 3.1ohm minimum for the CM-10 S2. Any particular reason for a receiver? You can get a Pre-Pro and amp(s) and have at least SOME of your system as 'future resistant'. I'm personally not a fan of receivers. They ususally have wimpy power supplies and don't do well with lower impedances. I have no idea how difficult the B&W model you have really is, but some B&W models really need capable amps. When you heard the speakers what was the amplifier? Did they have a receiver to demo with 'em?
