I, too, would highly recommend the Dynaudio 52SE over the B&W model.
I recently heard the Dynaudio 52 (not SE version) with a Cayin TA-30 (30W/ch using EL34 output tubes). The CDP was a Cambridge Audio (forgot model number). The Cayin-Dynaudio combination was very delightful indeed! Very natural sound, realistic highs, plenty of bass from such a bity speaker (rear port gets that credit). I think that you'll be much happier long-term w/ the Dynaudio. FWIW. IMHO.
