I don't have the exact same model, but very similar. I have the 803N and the older Def Tech BP2002, here's why I have 2 set of speakers. Your main goal is toward music, then go with the B&W, lots more details but less bass, which you could understand why. The Def Tech for movies is just insanely good thanks to it build-in subs. How about getting the B&W and a separate sub, that's probably makes more sense for you.
