MJC, I'm pretty sure you will be happy with the Hydra - I know I am. It will sound better after running in for 50 hours or so and each duplex outlet will run-in separately. I used a heater on the digital outlets for a day to give the run-in a head start and other people have used high wattage lights. In my experience, the Hydra is *much* better then the PS Audio P300 as the dynamics & involvement increased in a significant way.
I will be trying a Python Alpha PC on it soon so I can report on how it compares to the PS Audio Lab PC.
