If you want something that is going to sound nice with B&W Speakers take a look at the signature series ATI class ab amps or the Hypex Ncore ATI class d amps. Before you scoff at the ATI class d amps read some reviews because I know a lot of people do not like class d but the Hypex ncore’s are nothing like the old Ice power class d amps. The ATI class D are also getting very good reviews and are resonablily priced.
Best used five-channel amp?
I'm looking to upgrade my trusty Primare A30.5 amp to something a little more muscular a higher end. I have a Classe Sigma-SSP processor and B&W 804s units for the front and an HTM3s for the center. Does anyone have recommendations for used units? I've been thinking about the Classe CAV 500 or the Theta Dreadnaught. I'd like to keep it under $4,500 or so. Thanks!
