Yes as I have just gone through this. It appears that the PP is a modified Hubbel hospital grade outlet. I have three dedicated lines in my listening room and have installed two PP on two of them leaving the third with hospital grade outlet. Jumping back and forth with my amp from one with PP and the other with HG outlet the PP wins hand downs. The sound is more dynamic, peeling yet another veiled layer away from the music.
FWIW I would not worry too much about the nickel plating, though that was my concern initially as well. PSA's claim is that precious metal plating will not hold up well under this sort of application. Plugging and unpluggin gear I suppose. The bottom line, is that this is a very worthwhile tweak for $50.00, though it will not be a night and day difference, but certainly an improvement.
