I've enjoyed a PS Audio DirectStream DAC, which I purchased soon after it was released, and have added their P10 PowerPlant and DirectStream transport. The few times I've needed to obtain support from the company, I have nothing but good things to report.
I may get hammered for this, but I've been enjoying a McIntosh C2500 tube preamp and MC452 solid state power amp, which work very well with the PS Audio gear, and my speakers/sub woofers, so although the deals on the PS Audio pre and power amps were tempting, I'm "good" with what I own now, and I don't have a place to audition the pair driving the speakers I own (Focal Sopra No2's).
If I was looking to replace my McIntosh components, I'd snap up the PS Audio units as a replacement in a heartbeat. I bought the DAC without first auditioning it, as it had a money-back guarantee. I agree with the other posting, I think Paul is a genuine guy, not feeding us marketing BS to support his products.
