Power conditioning v re-generation; Shunyata v. PS

I recently decided to purchase a PS Power Plant - which as most know, takes AC power, converts it to DC, and then creates from that, new, clean AC power. It seemed logical to me that a new clean power source would be better than a re-conditioned power source.

However, now I am hearing that the Shunyata power re-conditioners (Hydra's) are better ? Is this the case? How can it be ? The PS Audio is producing new, perfectly clean power from a battery source.

QUESTION #2

If the PS unit is producing new power from its battery - why do they recommend that I upgrade the power cord from the wall to the unit ? It would seem to not matter what is going in since it is totally re-created as new power from the battery. Any explanations on this one ?

Thanks !
