Great choice there, the M3s.

I've had mine now for a number of years playing day and nite with never an uncomfortable moment. Not just "pleasant" but downright "Friendly"

Yeah! That's it, they're "friendly" speakers. (never thought of it that way, til now)

I use three as fronts and center and couldn't be happier. Only problem is my new listening room is just a bit too large for them and they seem to be strained some on the more demanding passages. Otherwise they're great, and easy to live with speakers.

Anyway, good choice and you have every right to be (excited)

Enjoy,
Rich.
