In regards to the PPP, it is not a pure regenerator, but more of a power conditioner. The PPP, from what I understand, tracks the input voltage and makes adjustments to it as needed. There is no regeneration, just conditioning. So in this example, yes a power cord would make a difference.
In a true regenerator, such as the P-500 from PS Audio, the input voltage is converted to DC then back to AC. In this case, a power cord shouldn't make a difference. That being said, the P-500 operates like an amplifier and we generally upgrade amplifier cords with excellent results.
