I dont have personal experience with pro amps, but in greek forums many people share the views and enthusiasm of Anthony for pro amps, and for the Behringer A 1500 in particular. (around 350 euros through internet shops). Some even use 4 of these to drive Magnepans. So, for me, the least I can think is, that there is no smoke without a fire.
And considering their price i dont think any 300 to 500 amp can stand against them
