Lionel, welcome. There's no need to be concerned about whether a receiver is "versatile". They just amplify sound transparently and don't care whether it's in a movie, music, or music in a movie. Unless the "larger" room you mentioned is really huge(in which case it would be too big for the M22s to do their best), the 340 should have more than enough power. As Craig mentioned, if you like the features, go with it

Enjoy the music, not the equipment.
