Maybe I can find out how much it costs. Not living far away from the compa…sorry, snake oil production facility.

Whoa.
Dude.
It's got a tube.

What about audiopath?

Maybe all of the above... multipath.

Mac -- as always -- was ahead of the curve.

It's audiophool homeopathic remedy.

Cool CRT. What does it look like. Is it a lissajous display?

 

[egellings]

It may be displaying one audio channel on the X-axis and the other channel on the Y-axis. If the FM station sent two same-frequency sine waves, one on each channel, and varied the phase angle between them, then it would show a Lissajous figure.

Unidirectional audio cables[??] Huh? OIC! Okay.
You be the judge, PaulMcGowan sez he "heard the differences", so it must be true.

"When the MI-3 is used with an FM tuner it will detect and display multipath reception. Multipath reception is the result of a reflected signal arriving at the tuner antenna slightly later than the direct signal. By rotating or repositioning your FM antenna it is possible to reduce the multipath reception. The Maximum Performance Indicator makes it easy to know when the FM antenna is oriented for the best reception of any station.

To show multipath reception the MI-3 displays instantaneous signal strength versus frequency deviation. Signal strength is shown as vertical deflection of the indicator display beam. Frequency deviation is shown as horizontal deflection. Multipath reception appears as a peak or valley in the MI 3 picture tube display"

right... I was... umm... making a play on words.
sociopath
psychopath
audiopath
multipath

I think we'd all agree that multipath distortion is pathological, though, right?

Hardware wise, both Macs and PCs are the same till recently when Apple change to their own ARM based processors. Btw, its entirely possible to get an x86 Mac to run windows, just need BIOS hack.

Indeed. "Hackintosh" is what we call them here. I actually have a couple lying around, though not in use anymore. IMO, they're not worth the trouble of keeping up to date. I suppose if someone really hates Windows 10/11, and or needs a specific program that only runs on Mac, but that's about it.

So it doesn't matter which ground the shield is connected to? That particular claim is pervasive. Can someone here explain why not or why it would work?

"direction" can make a difference for RF noise rejection.
if for example the cable has an additional shield only connected to one side ts better connected to the transmitter side.

But its in practice 99,9% snake oil. (made up number)
It relay can only help with noise rejection in super rare and unusually cases and even then i wont make a big difference.

Why is it better?

Why is it better?

You had to ask didn't you?
The explanation from the company "WorldsBestCables" goes like this:

"So in reality, the standard cable will have a slightly less capacitance (2964, 2497 etc) while directional cables (2549, 2534 etc) will have a slightly higher capacitance. And low capacitance cables (standard) will give you bright/neutral tones while the high capacitance cables (directional) will give you a warmer sound "
"Per the instructions, the shield is connected on the source end only which acts as a faraday cage which rejects external noise."

It can NOT 'act' as a Faraday cage if it does not provide 100% peripheral coverage!
This maybe similar to how a portable FM tuner antenna operates by using the single-ended shield cable over the +/- of the earbuds attached to it.
Snake Oil?

 

[Lambda]

Why is it better?

Usually its lower impedance at the source.
The noise has "usually" less influence on the side.
if HF/RF noise gets added it may add in common mode. This RF noise has relatively hard time traveling trough a normal audio cable especially if there is a common mode choke ferrite. so lees noise in total makes it to the receiver.

That's a ****** crappy thing to say, no matter who it is pointed to. Sup with the ?
Anyways:
We once had found a security issue with a coax cable which was part of a hardened MIL (multiple hardware) installation system. Cheapest, dirtiest and quickest way to provide RF signal integrity but not share a mutual DC ground was the use of double shielded custom coax: Where, one shield (insulated from the other) was grounded in the source end, with the second grounded on the load end. To keep the RF integrity of the sensitive transmit signal, the two shields were coupled to each other using chip capacitors at the load end. A floating DC-ground but provided the needed AC (RF) ground. This was an extreme example and only implemented because no alternative hardware could be substituted... [mumz da word]

Just bumped into this on Mono and Stereo page. Didn´t study the tales in detail, but when i saw the "Atomic Bonding" i had uncontrollable laughing stroke

Weze with you. And glad that there is a pathway back to sanity after the plunge into a the rabbit hole of multiple phantorgasms of ecstatic bliss bestowed by the latest kilobuck cables. It's ASR. If nothing else, it's cheaper.

Grounding is a state of mind. You often hear "he is well grounded". It means you know the that snake oil is oil stolen from the snake. Soon, social justice warriors will come and defend the poor snake!

Clark Stanley was a bad businessman w/his Snake Oil Liniment.

Ezra Kelley, a 19th Century watchmaker from Bedford Mass, was the first maker to commercially use oil from the jaws of porpoises and pilot whales to lubricate watch mechanism. In 1884, Kelley began selling this new oil (supplied by the Cook family), for a whopping US $5-$15 per gallon, which converts to around US $111 – $333 in today’s money. As a comparison, a barrel of modern crude oil, contains 42 gallons and sells for $90-$110. Whale oil was so expensive at this time due to supply and demand, but also for one other key reason – it’s lubrication properties were worth it.
