Need advice on what is a good A/C enhancer.

The PS actually takes power from the wall, filters it and then regenerates it into a ( supposedly ) pure & clean sine wave. All of the others filter ( in various ways ) what is already given to you from the wall. As far as i know, this also includes the Equi-Tech, but i could be wrong. Sean

Running balanced simply means that anything that is not commonly found on both phases is not reproduced and that both phases of the waveform will remain symmetrical. This does not guarantee removal of all noise since the noise could be found in the same time domain on both phases. As such, the balancing circuit would see it as being part of the original signal and NOT cancel it out. Balancing networks also do not guarantee that power being produced is a linear sine wave i.e. lacking distortion or reaching a clean peak of maximum amplitude. There is nothing short of regenerating the power coming out of the wall that will give you a PURE sine wave of clean power. To do this is not cheap, as we've all found out. This is NOT to say that the Equi-Tech or similar products are not well thought out products or are useless. They are simply a different approach that do not cover all of the bases as thoroughly. Sean
