I have a PS Audio Power Plant Premier (PPP) and it's sitting in my garage. When originally purchased it helped smoothed out my CD player and DAC. It functioned fine for years. A couple years ago I retired and added four dedicated 20 amp outlet. Later the fan in the PPP stopped cycling, running non-stop. I disconnected it to pack it up for repairs. Once removed, I never notice a change is my system performance. Therefore it is collecting dust. Note: during the time I used the PPP all my front end gear changed at least once, all having better internal power components.
