The M1's and EP125 are really 'bedroom speakers' if you ask me. They sound great in a very small room but once you use them in a living room, well, they get very thin.

If you have the cash lying around and still have the 30 day trial, return those speakers and get some much better ones. I'd go with either M22's or M60's for front, QS8's for rears, and if you upgrade the center, go ahead with either an M2 or a VP150.
