The Harbeth M30s are more refined and better balanced and it's difficult to think of anything better of a similar size. Before making that investment though it may be worth trying some form of isolation underneath your Dynaudio BM6s.
Either some form of footer (Herbie's etc) or some sorbothane hemispheres may help clarify the bass response via isolating the baffle from resonance modes which tend to blur the bass/midbass in particular.
Isolation can often help you to hear what the bass players are doing with dramatically increased clarity. Bass might actually become something to welcome, rather than some headache inducing noise.
Remember that virtually all smaller loudspeakers will be voiced with a bass boost in 50-100Hz region. Without it you would seriously render much music (esp Chamber and Acoustic Jazz) sounding limp. You wouldn't want flat to 50Hz and then falling off a cliff.
I'd try the isolation first and if that doesn't work, book a demo with the Harbeths.
