Sushi, although the majority of the time I listen to CDs on my stereo setup, I think that the better surround processing modes(CSII, DPLII, Logic7)make for interesting listening on occasion. I don't know if that's enough reason in itself to go multi-channel if you're not much into movies, but you could take a CD or two to a local shop to sample the ambience effects.

Enjoy the music, not the equipment.
