I always hate these, what do you like best posts. Unless, I need to try one. Now that I have sent my CRS+ packing to Tampa, I would like to pick up something used in a bookshelf that has the detail of the CRS+. I've probably got enough Polk Monitors and am now using a PSB 300 which I like a lot...but it does not offer the detail for a lot of music I now listen to...as compared, say, to my Black Sabbath days. So, what would you be on the lookout for in a used under $500 PAIR? A lot of speakers sound to me like someone has thrown a blanket over them and muffled the high mids and tweets.
