Looks like the CA discussions continue to go down the direction which has already been covered:
"the so called "claims" are general in that regenerating the USB signal and galvanically isolating it CAN/does improve SI, mitigate, noise, etc, to the DAC, which can ultimatley improve the overall sound. "
What comes "to" the DAC is not important. What comes out of the DAC is. DACs are designed with huge immunity to USB vagaries. High-end designers go to extreme measures to isolate what they know to be a computer interface. Even low-end ones like Behringer are well aware of such things. It is only in the imagination of non-designers that these things are impossible to do well inside the DAC and are in need of external help.
Our measurements prove what I am saying here, demonstrating that noise did not go down. That in the face of even noisy "SI" the standard DAC actually did better in extracting the USB signal and UpTone Regen.
There is no evidence that we can verify that any sound was improved. FYI I did listen and did not hear any such improvement. If someone wants to volunteer themselves to show that they can hear improvements with Iso Regen, I am very happy at my expense to come and verify such. Until then, that is an empty claim I am afraid. It is all based on lay assumptions of what these devices can do vs reality of audio electronics.
"Why did you and Amir single out Uptone? "
I didn't single them out. I was asked to measure one by a forum member as I have already noted multiple notes here and elsewhere:
This was in an email exchange about a completely different topic. This was my answer:
And this response:
I don't know how anyone could look at this exchange and decide I am out to get UpTone or singling them out.
BTW, this was also the case with the original Regen which member DallasJustice had purchased and wanted me to measure.
Folks on CA forum need to stop looking at me through the lenses by which they make decisions. I am not motivated by emotions, revenge, etc. My money does not grow on trees either and I like to apply it to many things other than these audio bits. But when genuine interest is expressed and with me being uniquely situated to make such measurements with professional equipment, I go ahead and do it.
"What about the 9 other ones? What claims are they making? The claims are very verifiable, tested, and proven to the satisfaction of the 95% who have tested them. These products work."
I don't know about 9 other ones. But I have tested the Audioquest Jitterbug and reported its ineffectiveness just the same:
You want me to test any other? My door is open. Send me a PM and I give you the address to ship them to me for testing. And I will pay return postage out of my pocket.
"The best way to verify what many are conflating these "claims" to be is to "prove" it by subjecting it to RIGOROUS testing which necessitates listening tests. "
That's where I am but I can't find a single one of you willing to help with it. I can't even get one person to tell me which music track is more revealing. Or what setup they exactly used. Or sit through a controlled testing.
So please put aside these empty word arguments and continued PR campaign and lay assumptions. They don't work with me. Step up and be constructive and then we have something.
P.S. I appreciate someone providing this answer to him on CA forum.
