PS Audio Power Pant vs Shunyata Hydra conditioner

Has anybody had the opportunity to compare a PS Audio power plant with MWI or MWII to a Shunyata Hydra ac conditioner? I have a PS Audio P500 and I think it's quite nice but I'm reading and hearing the Hydra is superior sonically in every way. The only thing is that it doesn't regulate a constant voltage but this may become a non issue as were moving to a newer place of our own and I will have a nice dedicated room just for the stereo system and I will put in a dedicated line if one does not already exist in that room.It was previously a video screening room and is 18feet by 13 feet. Any advice would be greatly appreciated.
