Hey all. I'm putting together a 5.1 home theater system. It will be used about 50/50 for music/movies. I need help in deciding on a receiver to run these speakers: Klipsch Center: RC 62 II Klipsch Floor: RF 62 II Klipsch Surround: RS 52 II Klipsch Subwoofer Sub 12 Is a receiver alone enough to run this setup or do I need an amp? I've never used an amp so this would be entirely new to me. I'm open to any suggestions. Edit to add: I'm hoping to spend $1000 or so, but understand if it can't be done this cheap. Absolute limit would be $1500. Thanks!
