I had the parasound A 21 250/425 and also the Hegel H360 that has similar power ratings, but is more neutral than the A 21 yet both didn't have enough to get the bass the salon 2 are renowned for. Also, if I tried to drive the speakers to 90+ db levels amps would go into thermal shutdown. The gent I sold the salon 2 to used Mac MC 601's and had no such problems, however he said that even with 600 wpc the clipping lights would occasionally start blinking on the Macs. I wouldn't buy any amp without trying first because they are quite good when powered correctly.
