"...there's a Ground Fault Circuit Interrupter (GFCI) for the two groups of four outlets that use isolation transformers, because their outputs are symmetrical (balanced), which produces a voltage potential on Neutral relative to Ground."
I have Balanced Power. I'll accept Martin Glasband's descriptions, which emphasize ground improvments.
The rest of the description, no opinion.

Probably underneath the board with the chokes.
Here's a blurry assembly line picture, lots of transformers on the bench:
An Equitech 2Q (20amp) is 3.5" tall and weighs around 65 pounds. (no board hiding the transformer)
The Niagra 7000 is 5.25" tall and weighs a claimed 81 pounds.
It claims "dielectric biased isolation transformers". Patent here - https://www.google.com/patents/US20150048916
So... What do you suppose is under the choke board that weighs around 60 pounds?
That patent application appears to describe a variation on the prior art of placing an electrostatic shield between the windings of a transformer. The difference is that it uses multiple shields with biasing voltage(s) applied to them in order to create an electrostatic field between the shields. The conductors of the transformer windings are in this field, and the claims are that the field alters the effects of the dielectric (insulation) of the conductors. For example:
"Primary and secondary windings (...) include a conductor through which the AC signal travels, and the conductor may be insulated by an insulation layer (...) composed of dielectric material. (...) the dielectric material may be biased by an electrostatic field formed to reduce the amount of noise or distortion the AC signal may experience while traveling through the primary and secondary windings (...). In this regard, with the reduced noise and distortion, the AC signal can travel through the primary and secondary windings (...) more efficiently."
And:
"In some aspects, primary and secondary windings (...) define a signal path to transform the input electrical signal into the output electrical signal along the signal path. In this respect, the signal path may travel from primary winding (...) to secondary winding (...). The signal path may provide signal transmission of sensitive electrical signals directed to audio, video and/or data transmission systems. The signal path may include undesirable electrical properties that impact the integrity of the signal transmission(...). (...) dielectric biasing may be applied to (or impressed on) insulated conductive layers (...) using first and second voltages to form an electrostatic field such that the undesirable electrical properties present in the signal path can be removed and allow components within transformer (...) to reach the stable electrical state sooner."
Hopefully the body of the application was better proofread than the "Field" statement:
"The present disclosure relates to electrical power systems, and more particularly a dielectric biasing circuit for the electro-magnetic used in alternating current devices."
In summary, it's the same sort of science that says applying biasing voltage to the insulation in cables will improve their performance.
Google's copy doesn't appear to show the full images. The USPTO copy does:

Yes I read that article as well. I found it interesting how one could take all the equipment normally plugged into what I assume is multiple dedicated circuits and in turn plug all that stuff into one power conditioner which is fed by X 1 AC Receptacle and not lose something in terms of SQ or power delivery to the amps.
I would imagine that if the volume was cranked up those big Dartzeel amps they could really start putting a hurtin on the power draw from the wall but then again, maybe he doesn't listen very loudly and the current draw remains under 20A all the time.
I have a quick question. I have a 7000 and am waiting for my Pass Labs X350.8 to arrive. I was told that Pass Labs amplifiers sound better when plugged into the wall (with the stock cord) rather than through a power conditioner. The stereophile article mentioned that unless all components are plugged into the 7000 it can potentially degrade the sound of the system. Any thoughts on this?
Also, I have a tube preamp and will most likely be running a Lumin S1 as a digital front end. I'm wondering if it would be better to just use Cards Clear Beyond cables into the wall with those components as it has built in filtering.

In my experience, it's better to plug your power amps into the wall. I recently tried my amps into the new, hyped up Shunyata stuff, and it killed all dynamics. ( I do think the Shunyata power cords are fabulous, and use them on the amps.) All of your other gear can go into the power conditioner.
Yet, there are a lot of variables and you will have to try it for yourself...
