I wish I had that direct comparison. I heard the 803D's at a dealer when they first came out and I liked what I heard, but I opted for the 802D's and I never did get them to sound great (in my room), including (later) using McIntosh MC402/C46; I have always wished I went with the 803D's, as I think they would have worked with my room better.
While the new B&W's are said to be easier to drive, they are still known to like a lot of power/current. There may be better amps out there to take control of those speakers, I may be wrong. My 30w integrated seems to have more authority than my MC402 did.
