I have klipsch RF 82's and Polk LsiM703's. For 2ch music I prefer the 82's, but for home theater the 703's blow the klipsch away. There is no comparison. Even for the 703 being only a bookshelf it still has way more detail than the floorstanding 82's. For home theater, the 707's would be the pick. With the 703's matted with a good subwoofer, it make a killer system that is very hard to beat.
