To follow up on this thread, I've finally got the full system together:
m3ti
NAD 520 bee cd player
NAD C320 bee integrated amp
It sounds great, and plays surprisingly loud. The amp only 50 watts, but provides plenty of power to get the m3's going louder than I would ever need.
A few comments on the m3's.
strengths: sharp imaging, great soundstage and smooth treble. The tweeter is nice. Overall the speaker is very pleasant to listen to. When I hooked them up to my tube system (anthem amp 1 etc.) they were very sweet sounding in a big 18' by 18' room.
Weaknesses: bass is there but not tight at all. It goes "poof" instead of giving a really good kick drum sound. there's something wierd going on in the upper midrange that isn't as smooth as the rest of the spectrum. Detail is good but not as good as other speakers (much more expensive speakers of course).
I won't gripe anymore though because I think these speakers are a really good value. Everyone that heard them at my house was very impressed and the general concensus was that the m3's are complete winners at their price. I'm happy with the purchase and will likely be keeping these speakers for a long time.
thanks for all the comments!
