I'm aware that silver plated copper isn't always liked when used with interconnects and speaker cables, however, I don't know the effect when you are speaking of power distribution. I'm sure you realize your long break-in of the Porter Ports was due to the cryogenic treatment which always takes a long break-in time.
You might want to contact @Ozzy and @Grannyring here on Audiogon because I know they have experience when it comes to rewiring power distribution units.
