Since you're in this price range and you have Atma-Sphere MA-2s, consider the Eidolon speakers. They are driven very well by the MA-2s and the two make a great synergistic combination. (It's the speaker/amp combination I live with.) If you're prepared to work on the rest of your system matching the speed, detail, neutrality and transparency of the MA-2s, then the Eidolons are well worth considering. They will be quicker and more articulate than the Andras, and they will be somewhat more neutral than the Kharmas.
