Please give me your insight oh wonderful world of avforum gurus! I am building as we speak and looking for a 7.1 surround system. My room is 20'x24'x10', and it should have relatively good acoustics due to care being taken during construction. My main concern is excellent surround sound- I will only be using the stereo about 10% of the time. I had made up my mind to buy Orbaudio speakers, but have been considering getting fullsize speakers- I am looking at Paradigm and the Morduant Short Avant series with towers for the front 2 and surrounds for the sides and rears and a center channel- combined with a subwoofer - i was thinking Velodyne but not sure. For recievers I am pretty much locked onto two receivers- the Yamaha RX-V1500 (is THX that much better), and the Denon AVR-3805. PLEASE let me know what you think- I have never had a home stereo setup EVER- and want to get it right the first time!!!!
