+1 for the LS50s or LS50 Metas mentioned above. I use the original LS50s, supplemented by a sealed SVS sub in a small room with great results. I have them about a foot from the back wall and approximately 2.5 feet from the side walls. From my listening position I cannot place the speakers, it just sounds like the music (sweet music) is coming from the front of the room somewhere. Zero plans to upgrade anytime soon.
