Tuning Collars on speaker cables - concept and any good?

Are dog collars acceptable knock offs?

Are these available for musical ministers?

😩

Watch this video it will explain a lot.

Yes of course, see my 'smilie'

>>>>No shirt, that’s kind of why he said it. 😀

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.

Are you volunteering? Please report results. Thanks in advance. 🤗

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.

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.

Which could be verified in about 2 minutes with an oscilloscope ...

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.

>>>>>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! 🕵️‍♂️

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!

Back in the day, when Simon Rattle and I used to hang of an afternoon, we listened to his early recording and critiqued them on a Bose Wave that he loved

But how can that be? Simon is one of the world renown conductors of our time. He should know better.......at least, about music. ( 😉 ).

TECHNICAL NOTES
Stealth Tuning Collars

Based on numerous listening sessions with various equipment, a STEALTH “T” cable with a tuning collar in the optimum position, the overall result (sound) is better than with the cable without the collar, BUT – with the collar in incorrect position the sound is not as good as with a cable without the collar.

The best sounding tuning collar position is different for every two pieces of equipment which that cable connect, thus it is impossible to point at the same spot (location) of the collar, giving the same sound as without the collar.

Finding the best position of the collar is a lengthy process and requires some time and patience. Usually two people are needed (one is listening, and the other is moving the collar). It is even better to have several people, and listen together

Like millercarbon wrote, the tuning collars make a difference after dinner and especially after drinks.

Are you in an artificial world?

When discussing audiophilia, this is often a question I wonder.

Why is "real world" in quotes? Are you in an artificial world?

Tuning collars are awesome for people who don't understand the difference between common mode and differential mode signal rejection.

Common mode noise is noise that appears on both signal wires equally. If the signal appears on both signal wires equally going to your speakers, then the "net" signal is 0 ... i.e. they will have no effect on the sound (at all).  Now, if your speakers were "grounded" which pretty much no one does, then there would be path for the common mode signal to go, but still ... same signal on both wires, so the speaker would not notice.

Why does this matter?  Because these "Tuning collars" go over both wires and hence can only impact common mode noise/signals.  Now, one could make the weak argument they reduce EMI, and that would be true if there was a ground path for high frequencies, but your speakers are not grounded, and your floors are probably not metal (and grounded), so there is not even a good capacitive path to ground for them to make any difference. I am sure there will be some made up argument about transmission line effects .... but I already sold all my swamp land in Florida.

Tuning infers a process that is somewhat predictable. Randomly mucking with the signal passing through a cable sounds like playtime for bored audiophiles.
Not that there’s anything wrong with that. Trying to distort your signal in a good way that is.  Fun! 😘 Fun! 😘Fun!  😘

Gosh, you’d think he’d be deaf. You know, what with all the high decibels.

Pretty much anything you put around a cable will affect the sound Mike. For good or bad, you can only decide for yourself by listening. That's the way it works.

Somebody has a bad attitude. I won’t mention any names. Have you ever heard of The Little Train that Could? I think I can, I think I can, I think I can... 🚂 Toot! Toot!

Yes some people love to play with new audio toys, especially fancy or esoteric  expensive ones and strain to hear or convince themselves of some meaningful difference so lots of merit there

That's what I used to think. Then I had an actual symphony conductor over for dinner one night. After drinks he suggested some Stravinsky. Right away he jumps up stop stop STOP! Walks over to the tuning collars, slides them about a half an inch, sits back down, raises his arms in that way- you know one a littler higher than the other- and I cue the arm back down. 

Sure enough, we were sharp, now it was in tune. So they totally work.

Just a big sham dude.

Back in the day; I always installed ferrite beads, on what I considered applicable wiring, within the components I built or upgraded.     Is there a correlation?      If so; it’s well-established technology, in some applications.

I’ve had those purple Shun Mook Original Cable Jackets and the spiral Cable Wrap, both of which were purported to absorb “reflected signal” in the cable. Both of those devices worked well (when correctly positioned) so the concept seems to be valid.

As effective as copper bracelets for treating arthritis! Stay away from Flat Earth technology!
