I like the sound of my M3 centers. One above and one below my SXRD.
Have you compared them to a VP150 or M22 before?
I had a VP150 before my M3s and was able to compare the sound before I shipped back the VP150.
You have to realize that I like the sound of the M3s. I have 3 pair!
I see you have M80s as well, quite the mix of different sonic signatures. Not so sure I would like it, (I sent back V1 QS4s becuase the tweeters were different and sounded a little off) but obviously you do and thats all that matters.
