So, I'm curious what the phrase: "...to affect harmonic energy change audio signals and systems" actually means.
ALL electric and/or audio signals are electromagnetic waves/fields. Just read Dollard, Steinmetz, or Heaviside...all electrical energy is the result from the interaction of dielectricity and magnetism.
So, how is this product different, and in what way? What is the transfer function and what is the functional response it is mediating? It's not explaining what the transfer function is, and what the functional response is. If it mediates some sort of physics-based functional response, it can be described by a transfer function. I don't get any of that information from the web page, so it reads like marketing-speak to me.

The phrase appears to have a grammatical error with an omitted preposition “to.” It should read “to affect harmonic energy change
to audio signals and systems.”
There is a superposition of a signal upon another signal. The ADD-Powr signal is a low frequency complex waveform. Essentially it is a square wave. The latter signal is the AC line. Our waveform and its programmed algorithm is proprietary information.
Suffice to say that in the time domain, a mathematically complex wave form such as a square wave can be expressed in the frequency domain as a harmonic series of sums of trigonometric functions. This was the discovery of the great mathematician and physicist, Joseph Fourier.
ADD-Powr creates a square wave pattern upon the AC line. Since it is of low frequency, it is not filtered away by power supplies. Instead, it passes on through the DC voltage smoothing stage. So what appears is a series or pattern of small (~.25-1.25v) square waves riding on the DC supply voltage.
It is here where the “smoking gun” action is located.
Since the DC reference has been altered with Fourier series waveforms, we now can understand what takes place. The Fourier series contain a fundamental and a series of related frequencies or overtones, simple harmonics. The harmonics are sine and cosine waves that contain energy or weight. The fundamental frequency contains the most energy and as the harmonic series scales up the band, the energy diminishes logarithmically in the time domain.
Now what used to be a direct current “x” voltage reference at 0 Hz, is now replaced by a direct current “x” voltage with a Fourier harmonic series!
Moving along, when a complex audio, “musical” signal with a fundamental of 100 Hz enters an amplifier stage it will resonate with, for example, a 100 Hz signal that, let us say, is the fundamental of the Fourier series that is riding on the DC voltage. Resonate means impart energy to something or vibrate with something of the same frequency.
So the input audio signal now sees additional harmonic resonant information in the form of the 100 Hz fundamental superimposed upon the DC supply voltage.
Every input audio signal to the amplifier will be affected by this re-referenced supply. This activity is occurring to all the power supplies in the hifi system.
These supplies become transformed to include harmonically rich Fourier series.
Thus, everything that is amplified in the system now has more “juice” at all frequencies along with increased energy, or voltage gain of various degrees depending on the frequency.
Do you follow this or are you getting a picture of what ADD-Powr does?
Now, you may be thinking, “well, how the heck do you do this?”
Ah, that is a question that digs deep into the magic and sorcery...that will have to wait...
Thanks for indulging me!
