I just got 2 pairs of these RS-150 bookshelves from the Christmas sale @ $199 plus $40 shipping per pair. Wow! Amazing! I'd have to say I prefer them to even the Studio 20's which I'm auditioned. My front Monitor 9s seem sloppy in bass and midrange in comparison. Even at $399 a pair, whoevers looking at bookshelves should give these a hard long look. I couldn't resist picking up 2 pair for $199 each and it seems like I made out.
