I have a ps audio P10 and A P5 . They are power regenerators they also have a feature called multiple wave .

I do not use them for power amps i use them for all other equipment . I do testing before and after to see what changes in sound are made. It some cases it helps and in others no so much. Can someone hear explain why and also it seems in reading it is a no no in this hobby . But yet most spend money on power cords, surge protectors , isolation transformers. As I have an PE degree and understand the how . But I do need some answers to this honest ones. The ones I have I know are very good at what they do.

Help please ok now help please

Why a power regenerator might help? Depends on how good the power supply design in the component, of course. I have seen some that are very clean and others, well, hmph.

Possible reasons a power regenerator/off-line UPS/SOLA/whatever might make a difference:

  1. Isolating line noise among components, e.g. incoming noise from the service feed and/or noise generated by component power supplies (virtually any type of power supply will kick back some charge out the terminals). Audibility is always debatable...
  2. Similarly, isolating low-level components from line sag and noise from high-power amplifiers, and possibly from other noisy things that might inject line noise like computers. If the low-level component is susceptible to line sags (something I have seen more in tube than SS gear but there are good and bad examples of both) then simply providing stable power could help.
  3. Something else.
