Hello aladinsan
I've had M22s, M3s, M2s (M50s) as well. I've used each of these speakers for music with a sub. In my systems, the speaker which worked best for me was the Axiom M3Tis. Not by a little, by a lot. They imaged better than the M50s. I think the soundstage they throw is better than the M50s as well. The M3s are more musical than the M2s.
Personally, I think there are things that bookshelf speakers can do that towers do not do as well. Disappearing is one - superior soundstaging, superior imaging. The M3s are stars. They are not perfect - but they're great.
