Here's an interesting thread from Audio Asylum:
You've got to listen to them yourselves. I wanted to upgrade from Dynaudio 50s to B&W Nautilus speakers. However, After demoing them in the showroom, I found I much preferred the Dynaudio sound. The B&Ws sounded muddled to me (at least the 805s did, the N804, I thought, sounded beautiful). Its so subjective, that you've got to listen to them and decide for yourself.
