I do not own the P5, but I do own a PS Audio P-600.
When I found that a Pangea AC9ES sounded better on my Furman REF20i than the previous Pangea AC9 I tried it on the PS Audio P-600 and was surprised the original Pangea AC9 was definitely better than the AC9SE on the PS Audio P600.
So from my experience I would say clearly different powercords can make a difference on PS Audio gear..
