May be a synergy issue:
I use an NAD C541 with a C350 into Tannoy System 8 (92dB/w) sudio monitors and get great results for jazz, blues, .... I tried this cdp into my AES/Cary tube pre and amp into Merlin VSM-Ms (which I use for classical) and thought it sounded very dull and lifeless. My guess is that you need to decide how attached you are to the B&Ws as compared to the NAD equipment. Try the NAD electronics with different speakers and the B&Ws with different electronics.
