I can't compare it to the PS Audio, but I was amazed when I first plugged my stuff into the Hydra. Improved everything -- clarity, resolution, and sound stage (expanded it tremendously).
I considered the PS Audio, Richard Gray and Hydra before buying . . . read reviews by experts and people using them and chose the Hydra based on . . . who knows? A feeling? It's hard to decide without auditioning, and to make sense of how this stuff does what it does, and how each does it differently, but I'm very happy with the Hydra.
