Saturn,
There is certainly no right or wrong about preferring a sub and mini monitor combo over floorstandings. Some people do prefer the bass of a subwoofer for music, but i'm just not one of them. The M22 and a sub provides an excellent sound.
I would recommend the M22 and a sub for HT users or for a smaller room whole heartedly.
We originally auditioned the M22 for this very purpose before deciding to also try out the M60. One of our biggest turn offs was the need for stands for the M22s, yet another piece of HT furniture.
As you have seen from my past photos, the furniture in our basement does not receive a great deal of budget funds at the moment...this was an obvious problem.
