Not sure how old the DM6's are but today, B&W manufactures many of their speakers with Kevlar drivers for the ultimate in stiffness and longevity plus tapered tube tweeter technology. The result? Superiour soundstaging, music reproduction, detail, and a term I use more than the industry does, ALIVE !! When I compare my B&W's to some older speakers I have, they are not subdued but come out at you in a big way yet still warm and not brash. The DM600-S3 series is their workhorse line and affordable to most of us in the middle class. But there are so many other loudspeaker manufacturers that produce beautiful products such as Vandersteen Audio, PSB, KEF, Tannoy, etc. Hope this helps.
