Such a great video, thanks for posting. Not one person that believe in this device has done a blind test showing that they can tell a difference. If you can only tell a difference in an informal sighted test that it really isn’t of much value. Either it is audible or not and these things can be done in a simple blind test. In particular with the claims that it is night and day difference. It should be easy right?

Here’s a review from a guy who is network engineer. He gives a different, more educated, response…

I did indeed do a blind test… with my girlfriend. She commented that my stereo sounded better when I made the tweaks. I made the change when just wasn’t home, so she had no idea that I changed anything but she noticed it immediately. She’s not an audiophile, but still noticed the impact of the change.

The amazing about the ER is that it is designed and made by the guys who have not had formal education in electronic engineering from any prestigious university.

Interesting but not a blind test. A simple blind test would be something like having another person randomly making a change, you listening and seeing if you can tell the difference. 10 times if you can identify 8/10 you can tell the difference.

While at Northwestern University, I got to know some of the people who wrote the computer chess programs that dominated that field for a decade. Lead by a Physics major, they came out of nowhere to beat the pants off high-profile, classically-trained AI folks from MIT, Carnegie Mellon etc. because they weren’t constrained by orthodoxy in their novel approaches to the problem.
They didn’t know the right way to do it.
That is a blind test. She wasn’t aware of a change and said that it sounded different. She was correctly able to identify how it changed.

There needs to be a sample size of more than 1. One could be a completely random event. To get a degree of certainty, There would need to be a sample size of something like 10 and getting 8 or so right out of 10 to prove the difference could be heard. The larger the sample/more right the higher degree of certainty there is in the change is affecting the sound.
What I’m describing is really a double blind test. The one you are suggesting is simply a blind test.
I had a non-audiophile make an observation that resulted in her asking about what changed. I then acted dumb and asked her how did it change. What you are suggesting requires the person to know that something has changed. I trust the double blind more than the blind. Others made similar comments, but they already knew I made a change.
All of this is academic. It made a difference to my ears… and those are the ones that count…

Change is only one part of the result, How has it changed and is it for the better or not? Different is just different without any contextual definition of what is different and if it’s preferred or not. One person’s preference might not be others too.
Then you can go into the why it might be different with respect to actual change that physically took place.
Bottom line is if you are making the changes and it’s works more pleasingly for you then you can be happy. But where do you stop…
Blind tests and those who insist on them are something I am not interested or concerned with.
Blah Blah Blah.
I added an EtherREGEN to my system, added an upgrade power supply to it, and decided it is worthy. Who cares if someone thinks this or that about it? LOL

No one cares, at least i do’nt.
With or without an EtherREGEN or some other magical sound enhancer, the music is not going to be better (or worse)!
Hilarious, these threads always end up this way!
If the naysayers dont think an ER switch makes any difference, thats fine, theres another thread going for that, fill your boots in that thread.

It’s strange that people obviously get so stressed when others hear / engage about products like the Etherregen. Aren’t we in era that should be more open minded?

I thought / had hoped at least within the hifi community things would be easier 
Not that it matters, because you are happy and feel there is a difference and aren’t interested in doing any kind of controlled test… but one person walking in a room is not a test of any kind. You could have here walk in the room 10 times, making a change without her knowing if it was in use or not and ask her which is better etc and record that. Getting 8 or higher out of 10 would offer some kind of assurance there is a difference.
But again it is all academic because you are happy 
Just wondering why IT has to be so complicated. You hear it or you don’t hear it. Simply as it is.
Expectation bias? It might be but for God’s sake not day after day.
Why not? It seems to me that it’s the kind of thing that would be self-reinforcing. You hear it the first time because of expectation bias, and say to yourself, “By God! I knew it would sound better like this!” And then the next day you are expecting it to sound good, and you’re happy it does, and so on and so forth.
