The first question...
I have not. I'd be curious to hear if someone did.
Unfortunately, for Shunyata, there are 2 products that cost less, act similarly, and have lots of good said about them.

I'm sure the "r&d" costs of designing a "power distributer" are quite high (/sarcasm end), but the other two products have been around a while, have alot of good things said about them, and in the case of the PPC, the user can upgrade the outlets if you wished to tweak it some.
This means that most likely, unless an AV magazine reviews one, no one but Shunyata users are going to buy them, and most of them between their Triton's and Hydra's probably have enough outlets already. Some brave fellow might come forward with some extra cash, taken by the looks and the want of one day owning a Shunyata, use it, report on it, and we might find out it's the best thing ever (though, I doubt it.)
Anyway, onto the second question.
Yes, upgrading the power cable on ANY power strip will affect the sonics, hopefully positively. I used a noisetrapper revelation with a Python Alpha Helix, a Venom 3, and finally use it with a Pangea AC9-SE, and every switch made an audible difference in sound. System noise, when plugged into a wall, didn't change drastically for me between cables, but the sonic signature sure did.
