Keith, yes, I have, as well as the 802D and 800D. As I said earlier, they are very nice speakers. The Dynaudio C2's are better though. I understand that all of this is subjective though, and that some may prefer the 803D sound. Not everyone understands this though.
The B&W were slightly more dynamic, but the Dynaudio's presented more timbral accuracy and better soundstaging.
In the end, I chose neither, but the Dynaudio C4's came in second to a pair of Verity Audio Parsifal Encore's.
If simply looking for dynamic capabilities, I think the Von Schweikert VR-4 SR's will best the B&W's in this price range as well.
Cheers,
John
