I concur with Dweller. In that price range Klaus Bunge of Odyssey can likely build you Khartago amps. I would recommend an upgrade to extremes. These amps for the money rival anything under $5k and I will tell you I have seen his bigger amps give $10k amps a run for their money. There are certainly better amps but these solid state units are pretty darn good. They are built in Indianapolis and based on a German design.
