Like @carlsbad said, all bookshelf have their limitations. Once you
hear floorstanding, its non comparable. I say for $800 price range, KEF LS50 is a good value on the used market I've owned LS50, B&W 805, Klipsch RP600, Elac Unifi UB5, Emotiva B1+. Of them all, the Emotiva are my favorite and they cost $250. My floor standing are B&W 803 and have been great to my ears. In my second room, the Bose 701 rock. Screw the specs, let your ears be the judgement. People bash Bose, but those 701 kill the book shelf speakera any day and they cost me $400 at a garage sale in 1995. Good luck
