Hi guys,
Would like to expand(of maybe contract)on one point if I may; And that is on "Forewardness" as relates to M3s.

In my experience only; when listening to my M3s I find them to place the vocalist right at the plane of the TV, while the M50s put the sound "about" one foot foreward. I know that statement is derived only from a population of one, but it's what I've found in "my" room. I also believe the M50s have a tad better midrange as well. (I did another A/B test on the M3/M50s the other night just before putting the M3s in back, just to see if my original observations a few weeks ago were still valid)

They were.
