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.

I noticed that while wearing my power pants, the hydra conditioner produces a much blacker background, with tight bass and killer mids and highs to die for.
What about the Audiophile APS (www.audiophileaps.com)? The claim to do the same thing as PS Audio, but with 90% efficiency. Anyone heard it?
I own both and I would not sell either one.

They both have their spot and I wish I could afford to own two of each for a real good A/B comparison.

They are much less expensive when purchased used, so they hold even more value.

Power cords are the next big question.
