Depending on what you want...
-IMO, YG and Verity are the most cohesive and "perfect" speaker but you must have the newest models. Possibly worth it if you value what they offer...
-TAD R1s are in your price range and I'd take them over pretty much anything other then a new YG or Verity speaker, from what I've heard.
Wilson, Magico and likely others including YG and Verity already mentioned have made some very significant improvements recently and you should be careful buying used as the new ones may be quite a bit better. I'd take a much smaller new speaker from these brands over much larger previous models for this reason.
