You may want to try pulling the speakers out from the back wall more. The further from the wall the M22's are, the better the imaging and depth are, atleast that's what I noticed. Glad you're enjoying the speakers, it'll only get better as either your ears adjust to the new sound or the speakers break in, or maybe both? I was quite satisfied when I first listened to my 22's, now i'm extremely pleased and couldn't be happier.
Really experiment with your speaker placement, it makes a HUGE difference, even just a couple inches will most likely be noticeable.
