it's difficult to make any assessment without a product in your hands.
The website doesn't list a price....
It does hint at filtering the ground line,however, as other line conditioner designers do and employ ( thinking of Shunyata).
However even here on the Tweaks asylum, grounding and its issues are becoming quite noticeable and being worked on. Bud Purvine's cable tweak is the simplest and cheapest to implement. The BGT is also in the similar vein.
It is my belief that the BGT in using a battery, sort of "charges" the ground line and basically pushes the noise there out of the audio bandwidth. You could call it a slight dithering effect, in a way.
In a detailed examination of some of Jack Bybee's power cords, it is interesting to note that his later designs use a purifier on the ground line and eliminates the purifier on the neutral. With just the hot and ground lead cleaned, the effect is even better than the hot and neutral which is what common sense would dictate.
We all take grounds for granted, but remember electrons are NEGATIVE and travel from the ground. It pays to take ground leads very seriously.
I have done some experimentation , a la Purist audio, and filled a tube around a ground buss bar with ferrofluid EMF field. Wrapping a copper wire around that tube to cope with the E field imparts a remarkable quality to the sound of an audio component. Deeper bass, more dynamics and a quieter background.
Ar any rate it bears experimentation
YMMV and FwIW

Surely the designer of the Bybee power cords knows the safety equipment grounding conductor connects to the earth connected grounded service neutral conductor at the main electrical service panel.
Surely the designer knows the current carrying neutral conductor of a two wire branch circuit carries the same amount of current as the hot conductor. And unless there is an equipment ground fault inside a piece of equipment no current should be travelling on the safety equipment grounding conductor back to the source, the electrical service neutral conductor. Of course unless a piece of equipment has a hot to equipment ground fault leakage problem where the safety equipment grounding conductor is carrying current back to the service neutral in the electrical panel where the equipment grounding conductor is connected.

Bybee is an quantum physicist and well acquainted with AC power. The fact that he filters the ground and the hot is an interesting concept, since most designers concentrate on the hot and neutral.
His purifiers handle up to 15 amps of current so there is little issue there.
Me thinks you are missing the point. Bybee now considers the ground lead as a significant part of the power chain, more so than the neutral, it seems,
OF course YMMV and FWIW
"And unless there is an equipment ground fault inside a piece of equipment no current should be travelling on the safety equipment grounding conductor back to the source, the electrical service neutral conductor."
If only that were the case... Yes, no significant (from a safety standpoint) power-line current should appear there without a fault condition but at the signal level in a typical unbalanced system it is smack in parallel with the grounds of the interconnects.
The topology of unbalanced home audio systems far predates both the "safety ground" business and most of todays HF noise generating loads. Not a pretty picture. (Not a senuous sound?)

JEA48 has a good link to an A'gon post from an owner of one,(see below) the highest of their grounding units I think and he said it was $3K.
