Tuning Collars on speaker cables - concept and any good?

If we need to look for trinkets to "alter" the sound our system puts out, perhaps we need to re-evaluate our components performance to find what's missing.
I used to have my ex wife try all these different makeup companies and application techniques, then one day it dawned on me.
I went out and found another wife that I liked just the way she was!

Which could be verified in about 2 minutes with an oscilloscope ... So the supplier must have scope plots on their web page of course?  .... We can just ignore that transmission line effects are impedance based and position of the collar would be meaningless I assume?

>>>>>Conclusion: the Stealth Cable

Collar works on the same principle as the Shun Mook Original Cable Jacket and the Cable Wrap from Highwire. It absorbs the reflected electromagnetic wave. Case closed! 🕵️‍♂️

C’mon, Geoff, you know it doesn’t work that way. People here who say they favor measurements, double-blind listening tests, and other "scientific" studies expect others to do that work for them. They don’t seem to have any interest in actually conducting such tests themselves. (It’s likely that many wouldn’t even know where to begin.)

In a way, I don’t blame them. In particular, blind listening tests take a lot of work to organize, and the tests themselves are no fun at all - they’re time-consuming and tedious. I also suspect that many who clamor for such tests don’t really believe in them, but simply reference them as a way to engage in argument.

I’ve suggested here for years that there’s a real opportunity to conduct such tests at an audio show. None of the measurementalists have ever shown an interest and of course with the current Covid crisis, it wouldn’t be possible.

Sure, you send me collars and I will test. I am fully set up, likely much better than the companies selling these. However, I am not in the habit of doing a vendor’s sales engineering for them, but in this case I will make an exception.

There was a thread going on Facebook, people more than willing to put up the money for a room, bring in their own high end equipment, etc. What do you think the odds are that suppliers will bring in their products for validation? No, those who advocate for them fully believe in them. No one references it as a way to engage in argument.   As most who advocate actually work in engineering and sciences, they would be more than qualified

Oh, and no one mentioned blind testing, as this is purely a simple measurement test.
