Well golly Ivanj thanks for the recommendation!
Okay there are several significant differences between the M-3's and the Dynastats. First off, the M-3's are much less efficient, and a much more difficult load. I would suggest 200 watts minimum for the M-3's; you can get by with 1/5th that on the Dynastats. And I don't know if this matters to you or not, but the Dynastats are six feet tall, whereas the M-3's are only five foot seven. The result is for someone my height (five sixish) when I stand up I lose the highs with the M-3's, but they're still there with the Dynastats. My listening habits are somewhat eccentic (sometimes involving dancing and twirling - all while fully clothed, of course), so losing the highs when you stand up might not matter as much to you.
The Dynastats will go deeper in the bass, but the M-3's will have superb articulation and coherence top-to-bottom.
I have a customer who spent quite a bit of time with the Dynastats. He has also owned Quad 988's and 989's, as well as Martin Logan Odysseys. He said the Dynastats were the best of the bunch, and the smoothest (he really doesn't like harshness). He now has the Sound Lab Millennium-2's in his living room, the next step up from the M-3's. He
tells me the Dynastats were nice, but simply not in the same league as the full range M-2's.
I hope this gives you useful information.
Now for the bad news. In my experience Aragon amplifiers do not match well with Sound Labs. The combination tends to be edgy. Obviously with the Dynastats you'd have more amplifier choices, but with the M-2's the InnerSound ESL amp would be my first recommendation in something (hopefully) affordable that would also sound very good and have plenty of power. I really gotta tip my hat to Roger Sanders of InnerSound (whose speakers the Sound Labs compete against) - he has designed an excellent amplifier for driving the speakers I sell. He is also a true gentleman.
I can put you in touch with an M-3 owner and one or two Dynastat owners, if you'd like. And, from time to time I can hook you up with used or demo Sound Labs - drop me a line if you're interested.
Best of luck to you.
