What no one who advocates seems to be able to answer, and this should be a really really easy answer, IS, if the results are so obviously different between these cables, "night and day" as is so often communicated, then why don't suppliers, of which there are many, do these double blind tests publicly, for all to see, so they can easily prove the value of their product. The great thing about a double blind these is there is no bias. Heck, the suppliers can pick their listeners, train them all they want, heck I would encourage it, but the control of the testing must be independent. If they can prove, via independent testing, with a given set of listeners, even a carefully selected group, that you can differentiate between good quality cables and their uber expensive cables, then all this back and forth goes away.
I know I can create differences between cables, i.e. really poorly constructed ones, and tolerably constructed ones, that will likely have audible differences for some listeners. For interconnects that will be very hard unless there are noise issues particular to that system, and for turntable cables it could be easy. However, once you reach a tolerable level of construction, the diminishing returns are not just small, they appear to be non-existent. Being able to afford an expensive system does not magically improve your ears or brain.
So .... perhaps someone can explain why, since the difference is night and day, no public independently administered tests by these suppliers? I have my theories about that ... what are yours? ... Would you trust someone who said their car got 200mpg? ... there used to be lots of claims of devices like that. What about those claims of "devices" you hook up to your AC line that magically reduce your energy bill by 30%. Would you just "trust" that? .... those both have been proven false.

The requirement is that test results can be reproduced, not
that everyone has to do the test before talking about it. To some level
it is an honor system. You are presumed of not lying. That is why
statements of conflict of interest exist. In this particular
back-and-forth about manufacturer’s blind testing, there is a huge
potential conflict of interest. Manufacturer may claim it in an
advertisement as a description of their methodology, but that is where
it ends.
