I have had my M22s (walnut/coffee stain/satin finish)for about 2 weeks now and they look and sound great. My plan is to build what will likely be a 3.1 HT system. The configuation of my room makes rears/surrounds problematic. The room is approx. 16 X 16 w/ 10' ceiling. My listening is 50-50 music-movies. The receiver I'm looking at is the Denon AVR 591 which seems to fit my budget and needs well. For the center I'm thinking VP150, but wonder if the VP100 is really all I need. The sub is where I am at a complete loss. I've been looking at Axiom, Hsu, and Elemental Design among others, but I'm not sure exactly what I should be looking for. Is the receiver a good choice? What about the center question? The sub, I just don't know. Any advice? Am I on the right track or have I stumbled into a fool's paradise?

thanks, jerry
