Game Changing Tweak

Pwerahera is using technical talk to discuss a very simple concept.

its called Power Factor Correction, or PFC.

Most residences share a common transformer. The power delivered on the power lines is 3 phase. The outputs from the 3-phase transformers are divided among residents. The neighbors’ electrical motor loads from air conditioners tends to alter PF. Residents tend to pay for more power than used. PFC can be used to re-align current and voltage both at ones meter and in your residential electrical loads.

But an AUDIBLE difference??

NAH!!

More snake oil!

Next.......

Every time I run into y'all discussing these objects of marvelous intent, my copper mesh body suit starts arcing in very personal places...

I can only handle this sort of thing for so long before having to 'ground myself' at the nearest earth ground.  It's like shuffle dancing on a wool rug in some ways....

If you are hearing a difference it is all in your mind.

I think technical information is useful. There's altogether too much opinion, however confidently expressed, without the technical knowledge to back it up. On this site, anyhow.

IMO

So I welcome  pwerahera's contribution. It's lucid, it's exact. What more do you want, wolfie?

Imo ADD-Powr is not snake oil. There's nothing wrong in trying to coin a catchy marketing phrase. 
It has nothing to do with quantum mechanics, nor any ooga-booga / snake oil devices. 
It has everything to do with science. 
Read the "about" page and then comment.

Apparently Bill, the designer of QRT, did indeed, use the word "quantum" to simply blow people's minds away in order to get attention and create a faithful following - and it worked!
Not based on rational science but based upon subjective emotion.
At the end of the day, all the products worked as claimed. But a rational explanation was not a part of the recipe, an odd and disconcerting marketing approach to say the least.
So, "proprietary technology" was employed and that became the explanation.

From perusing the web site, ADD-Powr is appears to be about increasing "energy", or the voltage of the audio signal through the generation of harmonics on the reference supply that are too low in frequency to be filtered away by the component power supply. They more or less resonate with similar frequencies in the audio signal. If the fundamental signal is low enough, then its resonant affect will be evident throughout the audio band. The driving fundamental must be a complex function composed of sines and cosines in various phases - that is the Fourier series. Or...perhaps it can be simply be a square wave!

That explanation makes sense.
