There is a lot of evidence that it works wonders. My listening room and the dozens of others who have one now. You may be talking about needing a particular reviewer state that it works. That is a personal choice I understand. If you have a dealer who will let you try it at home I am certain, absolutely certain, that would do the trick.
Yep ^that^ is anecdotal “evidence”.
We never seem to see some graph or scope reading showing something better or worse with or without it.
It is 5 hours to a local shop, and whether they have one, or not, I do not know… nor do I know whether they would loan one out.
Nor do I know if the thing would actually help as I do not know if anything is broken enough to need the thing.
Nor do I have a whole lot of desire to even try anything Gryphon, as I am pretty suspect of their customer service.
I have seen FFTs of my system during using the DAC as ADC, and was surprised that I had some spurs in the spectrum with no apparent sound playing. And was able to do some cable and ground hygiene and reduce that stuff.
But it was below audibility before I started, so another 10-20dB lower than that seemed lower than low enough..
Hence I am not sure whether these things are like the emperor’s new clothes, or whether the other people have problem that I do not have, or whether I have some FOMO. And then the hand waving in the video left me with the feel that the fellow is a slick salesman.

Basically everyone that got one of those and kept it, is in a group that it either works for, or they believes that it works for them.
Hence it is a weighted group.
And everyone that did not get one, either is already happy, or doesn’t believe that it’ll work, or doesn’t need it.
And then there is a swath of people which I may be in with, that do not know if they need such a thing, or do not know if it works, and are unclear whether it is anything more than just a powerstrip with a nice lion logo on it.
If we like to listen to the people that one - then would get one.
If we like to listen to people that did don’t get one, then we would not get one.
And the company did not do a whole lot towards providing clarity with the shuckin-n-jivin in the video.
