i have sony crt projector with a skyworth dvd player. ive been using the same pioneer pro-logic stereo for sound for 7 years now and its time to upgrade to dolby digital. is there a system speakers/amp/sub that will fill a good sized room with sound? i like the way klipsch speakers sound, but they are all quite expensive. i am hoping to find a surround sound system for $2000 or less. is that possible?
