A/D/S M15 Speakers

I heard the M30s once, at an audio show in LA. They sounded *very good*, with imaging superior to any other ADS speaker. I've never heard the M20s.

I used to own the M15s. The Ms image better and are capable of playing louder, but the tweeters on the M15 never impressed me. The M15 cabinets were also a somewhat resonant, and I always wondered if that colored the sound. The Ls were better in that regard. IMO, both of these speakers are bested by products with the latest midrange and tweeter technologies.
