Looking for a power conditioner/regenerator/filter

OK I'm in the process of looking at a way to clean up my AC power. Like everything else there are tons of options. From my reading I have narrowed it down to Hydra, Bybee, and PS Audio. The PS Audio sounds nice in that it will regenerate "clean" power. I have heard people rave about the Hydra and Bybee V2 and I see they have the Stealth now.

Anyone have any experience they can share? My amps are 300B tube monoblocks. My front end is DAC and Music Server.
