LOL! YIPES! That EP600 makes the M60s look teeny.
The room looks very nice, and comfortable. Nothing to be ashamed of at all. You might experiment with aiming the M22s in the rear a bit more straight out from the wall, as opposed to the downward angle at which you have them. If you're heavily into multichannel music (SACD/DVD-A), that's probably the way to go. But, for HT, the idea is to disperse the sound a bit, rather than have it shooting directly at the seating area. Regardless, if you prefer them aimed directly at you, that's the way they should be set up.
