Quad 21L (I own) or the Epos M15 (Only other speaker in the price range I would consider).
Quad is more detailed, Epos is a hair more musical. But I haven't heard them both in the same system - and I heard the Epos with MUCH better equipment than what I own. The Quad's are also much more revealing than the Epos' and the finish - if you have a wife/gf you really need to see the Quad's in Piano Black or Birdseye maple - wow.
