I use a pair of Kef LS50s in my bedroom system, supplemented by a SVS Subwoofer that I had lying around. If I were starting over I'd probably go for a Rel sub but the system sounds so good now that I'm loath to disturb it. The speakers simply disappear, the stereo image is there and on pieces of music such as Brubeck's Take 5, I can pinpoint the exact location of each instrument including the breadth and depth. I drive them with a Peachtree Nova 150.
