I've had a pair of M30's for about 6 weeks. They replaced some Vandersteen 3A sigs. I prefer the Harbeths; they are warmer and have wonderfully detailed midrange, with less emphasis in high end detail (which makes them a bit "forgiving" in character, which I like).
Dweller, I have the same curiousity that you do about the rest of the line (as seconded by Drubin): How do the M30's compare to the Super HL5's? The M30s are just a bit forward, or, as one of the reviews noted "piquant." I might prefer the HL5's, if they are more laid back, and I would urge you to try to listen before you buy (which I did not do). I did hear some Compact 7's at a dealer (after committing to the M30s, as it happened), and was favorably impressed, generally, although I think the M30s may have better bass. The M30s have quite remarkable bass for their size.
I also completely agree with other comments that you really need some power to drive the M30's properly. I used a VTL 150 in triode mode that seemed to run out of gas in the bass; a BEL 1001, which worked fine; and have settled on an ARC VT 100 MkIII (which was in the shop when I got the speakers).
Good listening!
