I have to admit I'm in the same situation -- M22s probably would have been fine but I ended up getting M60s anyways and never looked back.

I am currently using the 60s primarily for music (HT is in a small room so M2 mains are doing fine) but they will go back to being the HT mains in a few months when I move into a new house with a much larger HT area.
