That is some serious power you have for a desktop system. I would also look at the Anthony Gallo Strada 2 and the Magnepan Mini setup. Both have been described as the ultimate desktop system. I actually have the Gallo Strada 2s, just haven't had time to set them up yet. You have the muscle for them both, they are in your price range, and they are really wonderful in the near field.
