Gotta agree with Bren on this one, and raise his input by 50%. I've used three up front for many years and couldn't be happier with them.
If you look on line for "Professional" reviews of the M3s, you'll find a dozen or so going back to about 2000. The only bad comment I'd read on them was that one tester found them to be a little b..., b... uh, can't say it, it's the "B" word. We don't use that word here, it's a "Rocket" word. (ok, but don't tell anyone I used it; one tester found the M3s to be a little too "bright")
My ears prefer the M3s, yours may opt for the M2s, but don't discount the M3s just yet!
