Haven't heard much about the other companies, but if the Hsu performs anything like my VTF-2 (a bit bigger woofer and just a hint more amp power) you'll be very happy. Hsu has a solid reputation and the other usual suspects (epik, svs, eD) are either out of your budget or in a different finish.
If you can put up with the non-piano black finish, though, the eD A2-300 gets a lot of positive press.
