I've found that Ayre amps sound great with B&W. You could get away with a V-5xe with the 803D but you'd really need the V-1xe or preferably, the MX-R, for the 802D (and they definitely don't hurt for the 803D).
Amplifiers for B&W 803D/802D
I'm new to high end home audio (have extensive high end Pioneer ODR system in the car) and am looking for amps to pair with either B&W 803D or 802D. My local B&W dealer only sells Rotel and Classe and hasn't been able to set both amps up together so I can listen/switch between the two. Is there a significant difference in sound between these amps with these speakers and is it worth the expense? Are the Classe amps reliable long term? Has anyone heard B&W with Mcintosh amps? I listened to Mcintosh with Infinity speakers that sounded great but can't find a way to demo Mcintosh with B&W. Thanks a lot.
