I have been told that the majority of modern classical recordings are mastered on B&W loudspeakers. I own a pair of Nautilus 803's and they sound wonderful with all types of music. They have the most natural midrange that I have experienced. I would say that they are more geared for my classical collection than my rock collection. The Dynaudio is an excellent speaker as well. You will not make a mistake by going with one or the other. I believe, however, that B&W is designed primarily for classical music playback and therefore may be a better match for you. Good luck.
