I've had a PPP for over a year, feeding power to my entire system, with no clicks or other problems. The positive difference it's made for my system has been huge. Lucky so far... I'll knock on wood.
PS AUDIO PREMIER
Years ago, I owned a PS Audio premier power regenerator. I enjoyed having it, but had to send it back because it was reacting to some kind of problem with the incoming power line. Sometimes at night I would hear it click as if it was adjusting to something on the AC line. Thing is, it was turned off. PS Audio sent it back after making a new grounding scheme for it. It was no use,same trouble. I sold the unit and went a different direction. So, my question is, has anyone else had issues with this unit? I am tempted to buy one again hoping for a better result< since they are going for 'cheap' nowadays.
