In that case I'd be looking at a Rotel. The RA-930 amps should be available for that sort of money and I think you'll find it hard to beat them with that budget. They are very good amplifiers indeed.
There also seems to be quite a few Kenwood KA3020SEs around that sort of money at times, although some find it a little harsh. Certianly not as well balanced as the Rotels.
