DON'T BUY A 2 CHANNEL for music buy a Three because the Denon will not be able to match the volume of the center with a good 200watt 2 channel amp... You need to buy a good 3 channel amp to get the same volume/current across the front.
Since your room is so small and I use to have 2000watts 8ohms RMS in a 11'x11' room plus an 18" Velodyne Servo Sub.
I can say one thing.. Treat the room (first order reflections, bass traps, and damping behind your listening position) You system will clean up and effects and imaging will sharpen, and suddenly you won't seem to need as much power!
