You’re loosing your time here... Nobody will seriously engage in an open discussion. The first thing they will ask is to show measurements. I’d say my measurements are my one ears. The rest I really don’t care.
Two things:
1.
What other than good comes out of measurements and testing the thing for proper operation as claimed? Maybe it runs poorly. I tested the
Uptone ISO Regen USB from them. When one thinks of "regen," you would think the USB signal is generated stronger. Well, turns out the ISO Regen performed worse than $20 commodity USB hub in its inability to deal with weaker USB signals/long cable lengths. See:

With a shorter cable it produced this output:
This is what happened when I doubled the USB cable length (top graph):
The Uptone USB ISO Regen clearly was losing data. So much so that the effect was quite audible:

We LOVE, LOVE, LOVE listening tests. What we don't want is what you think you heard, as opposed to what the sound waves did that hit your ears.
I can buy one of these Etherregen boxes, take out the guts, and put in a $20 switch in it, and get upstanding folks like you swear it still improves the sound! That it lowers the noise floor. Increases the soundstage. Lifts veils, makes digital less harsh, makes digital like analog, etc.
How is this possible? Simple, perception is not the same as sound that the ears capture. I can play two identical files for you and have you say one is better in all the respects per above. I can even do that if you think the "better" version is going to be worse!
When you compare gear with your "ears" you must do it in a way that avoids the above pitfalls. That calls for not knowing which is which. And running enough trials to make sure you are not getting lucky with one or two guesses.
This issue has been known for decades in audio research and for that reason, no one that does this work seriously will accept your "listening" results to have any value.
I am so confident in above that i
f you can perform this test reliably, and tell the difference using ears with this versus another switch I will donate $1,000 to your favorite charity. I will give you $10,000 if you can tell Ethergen reliably form another if you give me $1,000 if you fail.
Likely you won't take my bet. If so hang low, listen to what we have to say. We are not stupid here. And nor is the entire audio research and engineering. Give us a bit of credit that there is a reason we judge things the way we do.
