Power conditioning technology is mostly a band aid for something that is - in my opinion - the single biggest problem in hi-fi. Much like up-sampling and re-sampling, if the source (in this case, power) is garbage, you can only do so much to clean it up. Even the PS Audio conditioners that regenerate AC are only 60-80% efficient. Besides, is there a single piece of audio equipment that natively uses AC power? No, everything requires DC power.
AC is useful for most uses in a typical home - appliances, lighting, etc. But hi-fi is a critical application of DC power - why on earth should effort be wasted on trying to extract it real time from garbage AC when battery technology now exists to bypass it?
