The ADD-Powr Sorcer and Wizard are unlike traditional power conditioners.
They are not filters, nor isolation transformers, nor power re-generation devices, nor inductive energy storage devices. They are harmonic resonators that "condition" AC power in a unique manner.
The layman's explanation is at the web site.
Pulsing the AC line at a very low frequency (and with fast rise/fall times) will result in the superposition of a square wave upon itself. The idea of a harmonic content derives from the fact that a square wave is comprised of a mathematical series of multiple sine and co-sine wave from the fundamental out to infinity., as discovered by Fourier.
If this low frequency square wave signal finds its way past the power supply rectification stage and onto the DC line, then this altered reference will unleash the harmonics into the amplifier.
The idea of resonance takes over. The audio will be completely affected by harmonics from the minute (millivolt) square wave riding on the DC line.'
The actual power supply uses about 500mA at 9 volts, or 4.5 watts.
Traditional power conditioners do what they do well, but none of them offer the harmonic benefits to recorded music like the ADD-Powr products. And they will improve the audio signal energy (signal-to-noise ratio) by as much as 10 - 15% throughout the audio spectrum.
What power product can do that?
Answer: none.
