I went from M2 surrounds to QS8 surrounds. Much better for movies, and I would say maybe 90% as good for music. Definitely better for music than your typical dipole. I did slightly prefer the more localized sound of the M2s for music though.

Having said that, for anything but a "mostly music" system I would go with QS8s again.

The real solution, though, is to run a 7.1 system with QS8 surrounds and M2/M22 rears, then plug the surround channels on your CD player into the rear inputs on the receiver, so 5.1 music plays on the rears instead of the surrounds. I haven't found a good trick for getting surround info to only the rears when running stereo content expanded to 5.1 or 7.1, but normally I listen to stereo content with just the mains anyways.
