The room i am building is approximately 1600 cubic feet or 11x18x7.5. I have a projector and screen. I am shopping around for speakers. But I need to know what AVR in the $1000 range would be best for that size room. My initial setup will be 5.1 but i would like 7.1 capability for future upgrades. I have been looking at Denon, Harman-Kardon, and Pioneer. Does anybody have any suggestions or opinions they would like to share?
