Here are a few things that proper power conditioning can correct:
The most important is the 5th harmonic. Fluke instruments printed a white paper on this subject some 20 years ago. The 5th harmonic (300Hz in the US) can cause power transformers to become noisy, power rectifiers to radiate noise, and certain types of AC motors to possibly spin backwards.
DC on the line can cause saturation of toroidal transformer cores and should be blocked else the transformer can become quite noisy. A second harmonic on the line can do the same thing.
High frequency noise can cause problems in digital gear but otherwise is not likely to do much to analog gear if the power supplies are properly designed.
Any skeptical engineers out there? If so, consider the fact that the best power conditioners were made by companies that directed their product at the commercial/industrial market. Elgar is one of those companies. If clean power did not help, companies like Elgar would not exist. If there is skepticism, it exists out of ignorance, which is easily curable.
