In my personal experience (although peeps might not agree?)I have gotten more dramitic results on digital and pre-amp products than amps when changing pc's. I don't know why seeing as they draw less power, just my experience... If I were in your position, I would take a long look at Pangea pc's from the Audio Advisor. (not affilitated) It seems there are a large number of happy users here on A'Gon, and they are right in line with your budget.
