Update May 17.
PS Audio left the system earlier this year after I had to question it's contribution in the end. It sold very quickly and the new owner is delighted with it which is great. So, the design for a replacement power supply began last Xmas, and the finished (well, almost) in in use now, and the sonic difference between mains wall outlet, and P10, is an eye opener. I will add more detail about it, but this afternoon a colleague will bring a Kemp conditioner that he uses for comparison, (i don't think there will be any btw). See my system details and pics for more info on what I built. All i can say is it is by far the biggest single jump in sonic ability I have ever heard in my system here, and my wife agrees for once, which means something!
