Pwr Cord Upgrade for PS Audio Pwr Plant Premiere?

I would like to pose a question regarding the need for any type of power cord upgrade for a PS Audio Power Plant Premiere (PPP) power regenerator. If I understand its workings properly, the PPP will take “dirty” line current and, through its electronics, regenerate it into a consistent source of new “clean” AC power. It is not coloring or conditioning the existing power feed in the classical sense. It this is true, what benefit would an upgraded power cord provide? If “dirty” AC is being regenerated into “clean” AC, does it matter, within reason, how “dirty” the power is to begin with? So, back to my question….would an upgrade of the power cord for a PPP provide any benefit at all and, if so, why?
