Well that was my point.@im_gumby as @Holmz stated you won't hear a difference. The premise that these snake oils wires sound better is derived from wires that conduct about 1MHz and higher RF signals. For a lowly 20Hz to 20kHz audio signal there is no improvement. So it is a truth that is stretched way beyond reality/a half truth and then proposed as a fact.
There is some science to back up what they are doing.
Now is it snake oil? Yeah. Not because the science isn't real, or that there isn't a measurable difference.
Its just that the difference is well within the noise and can't be heard.
One of the better respected YT and Audio online mag did do a test of these higher end cables.
They did find a measurable difference. So the science is there. They did capture some of the reviewers describing the sound quality of the cables.
(They took notes on what they heard and while done independently... several of the reviewers had the same description in terms of sound. So while I probably couldn't do what they did... clearly they heard something.)
In terms of audio... some claim that they could hear a difference. Placebo effect? Sure. Could they pass an ABX test? I don't know.
But I have to wonder... better quality parts and shielding can change the output in terms of db. So if something is slightly louder... do you hear more things in the music?
That said... another YT guy who does sell high end components and snake oil components. (e.g MIT speaker cables that retail for 100K) he had his buddies do a blind test of high end cables against cheap wire. They could tell a difference but preferred the sound of the cheap wire. A bit of egg on his face, and he said that of course there were diminishing returns when you spend $$$ on components where you could have spent $$ instead and had the ~80% of the sound quality for a fraction of the price.
Personally, I own an Onix Alpha dongle.
Now I've used it with both a cheap USB-C cable that was rated for 480Mb/s and a USB-C cable that was rated for 40Gb/s.
The 40Gb/s sounded better when running it from my PC. Less of a difference when running the dongle dac from my iPhone.
Part of the difference is the amount of power across the USB-C connection and that the 40Gb/s has better shielding.
When I used a different cable that had a USB-A connection to a power source, and then the USB-C for data... using an external battery improved the sound.
Now there isn't any placebo effect here. Multiple people have experimented and had the same results. I did find that if I tried this w my laptop using an external battery no appreciable sound difference. Both were still better than the device getting power from the phone. Also, its known that the dongle is power hungry. It doesn't work w all phones and this is a known problem. So yes cables can make a difference. (One guy too a laptop brick as the input for power instead of an external battery. Said he loved the sound. I tried this w my macbook's brick. Again better than the iPhone, but I couldn't tell a difference from my laptop.)
Now back to speakers...
Of course YMMV depending on the cable, the speakers and the amp.
I guess my current set up isn't worthy.
And like someone earlier in the thread which said you should spend X on your speaker cables based on a percentage of your overall cost in components?
That's a joke.
