Yes, I've been looking at crutchfield's site.. Right now they've got the rt55's for $400 a pair and the IL30's for $600 (including an IL25c center channel). Now I've heard the Polk bookshelves and liked them. I'm not sure if I've heard the specific model of Infinity, but I recall liking the sound of Polk better. It won't be convenient for me to go out and find some IL30's to listen to for a little while, so I thought I'd get this forum's opinion of these speakers. Keeping in mind that with the Polks I'd be getting a CS400 center (another $400). Of course, other recommendations in the price range are welcome. I've been hem-hawing around for a while and now it's decision time.
