I got the Matrix M-stage a couple of days ago and DAMN I Can certainly understand why it's a popular pairing with the Q's.
Damn, it does sound great with the Q's!
Right now I'm using a Matrix Quattro amp, which is just a balanced M Stage.
I use it SE with my Q701.
I find it hard to see why I would want to upgrade my amp.
