AC Power

24.251.148.169

Hi,

What is the technical basis for power conditioning, AC purifiers, etc.?

Several very reputable manufacturers of high end components do not recommend using any them (actually stating it is best to NOT use them). I have also read quite a few posts stating that a high quality power supply should isolate a component from AC issues.

Does this mean that under voltage, over voltage, and line surges within a reasonable tolerance are a non-issues? What about noise on the AC line?

Is there any scientific/technical justification for spending money on power conditioners, re-generators, filters, and such?

L.
