that's incorrect. you can find many instances where we'll be able to perceive a difference. of course it will depend on many variables and those variables will usually have no reason to be significantly different in the first place. like if 2 devices are 800m away from one another, the conversation about how a 1m cable might result in audible differences compared to the 900m cable is pointless. same with how a given interconnect has no reason to be vastly different from the standard of that particular type of cable(unless done wrong on purpose), so wondering if a 6000ohm USB cable would affect the sound is also irrelevant in practice because a USB cable should not have that impedance.
this makes for a sort of self prophecy where cables within the standard will not significantly affect the sound compared to other similar cables for the very simple reason that they will have similar electrical specs. in that respect, I'm with you that worrying about cables is often a waste of time, and spending big money on cable is almost always a waste of money.
but I've had IEM cables causing clearly audible differences, starting by the most obvious, a difference in overall loudness, or if the IEM has a chaotic impedance curve, a difference in the FR. that is helped by how little standards we have for such cables, and how we have even fewer standards for DAP outputs and IEM specs. the bigger the mess, the more likely we are to end up with something acting up in a more significant way. it can and does happen. it probably shouldn't and will usually not amount to anything more than inserting my IEM slightly deeper or changing the tips, but audibility is not out of the picture all the time.
about all the nonsensical claims of causality between the metal and a certain way the sound is going to be affected, I'm fed up with it. although it's certainly a very good example of a popular logical fallacy where a vague sense of correlation suddenly implies causation.
The math showing how a cable can make an audible difference is no mystery with analog signals. If the measurements can be provided, the difference can be calculated.

For digital signals, there are specifications that should be adhered to for the specific application. Again, all of these parameters can be measured and verified.
The problem I see is mostly with perspective. Most people refer to the cable as changing the sound when something is noticeably different, but it is typical that some distortion is already present, only that perhaps some cables allow this distortion to be audible. The distinction is important when discussions are made concerning how different cables can improve sound quality. Is the problem the cable or the source of the distortion?
