No experience with PS Audio amps, but do have their P10 Power Plant, DirectStream DAC and PerfectWave transport and like gshepardbuster have found their support to be really excellent!
I believe PS Audio has a 30 day money back guarantee, if you purchase their products new, thru them or one of their authorized dealers.
