Approximately so, maybe. IME cable construction can matter. Also, none of us probably wants to use wire of visibly corroded quality if we can avoid it. Whether or not single crystal can ever matter in the slightest for audio use remains an untested question for me. IMHO deferring judgement on it for now can be a valid option.
Don't agree with the sentiment that any one member can set limits to what the rest discuss though. Consider ignoring these threads instead if you find no value.
I would imagine if you are doing experiments that involve hundreds or thousands of amps (think LHC for example) then every little bit of resistance has to be accounted for, even though these conductors may be supercooled. There will be a host of other factors that warrant special conductors than only JN is really qualified to expound upon.
Thankfully, they are of zero consequence in any known audio application and with any known speaker load. As long as the cable can conduct the requisite current without too much voltage drop and/or affecting the amplifier damping factor (assuming the latter floats your boat), you’re good to go.
As in most of these things, spending 100 bucks on getting your ears flushed an cleaned by a audiologist will pay dividends.

This is what is generally known as "Hand waving." There was plenty of that in the other thread.
If art lovers were claiming that "prints are inferior, I can easily tell a print from an original", but when tested they couldn't - it would be the same. You would claim that since they had never seen the original before the test, how would they know which is the original? That is an argument, but it is not a very good one.
Keep trying to invalidate the test, it's good practice for me to defend the test when I do it again - hopefully better.
As noted by Whitlock and Putzeys as well as many others. Of course adding a second braid to a coax cable is far to sensible for any LC-OFC afficianado to actually try...
For the superconductors, there is no resistance. However, all the magnets have to be spliced together somehow. For the big cable magnets running 13kA, and the upgrade magnets we are testing now at 18kA, the solder joint is the biggie. The lap joints are 6 to 10 inches long, and have to be less than a nano-ohm so they do not warm up with current. We can measure the resistance only by measuring the voltage drop at full current, we cannot measure a nano-ohm at room temperature. Even at full current, the voltages are very small so the measurement is difficult.
The explosion at the LHC two weeks into startup was a consequence of a bad solder joint.

Assuming JN tells the truth, I cannot discover any bragging. Do you have a problem with people with more success in science than yourself?
In general no, but I'm afraid JN is not doing any science. That would be obvious for those who have even a foggy idea of what science is.
Indeed.
Cable behavior can be more complicated than a simple DC resistance model might suggest. Even true for speaker cable made of zip cord, as Hans Polak found when compensating zip cord impedance with lumped elements.
Lots of discussion about making zip cord sound better in the thread at: https://www.diyaudio.com/community/threads/zip-cord-for-speaker-test.371099/post-6686399
Firstly: I think it is a bit strange and somewhat funny that some people seems to get so VERY emotional on the subject of cables. 🙂
If the crystal structure can alter the signal? Absolutely 100% guaranteed that it can. The real question is: Is the difference audible? Will the percieved sound of the resulting music reproduction, in the end, be better or worse?
Can a cable alter the signal? Absolutely 100% guaranteed that it can. High resistance will attenuate the volume - taken to the extreme - no signal at all will pass. High capacitence will alter the signal, high inductance will alter the signal. RF, EMI and so on...
Personally, i havent to this day found any significant difference in the sound of different cables. But i havent done any really serious, extended AB-tests tests, or double blind tests. It might be worth it. I really dont know.
Well. The 100% sure thing is: ALL existing cables in the known universe ALL alters the passing signal in anything from a extremely small to a extremely LARGE way.

Not really, its the first call tweak for people who don't understand how things work. Then you get onto resistor/capacitor/opamp/tube rolling and reports of veils being lifted and wives in kitchen giving approval. Hifi reviewers reporting on how they fine tune their systems by swapping cables around reinforces the fact that they are the seasoning to reach audio nirvana.
I think you are just trying to stir **** at this point, which is not unusual for you. Hans was not swapping cables to add some little nuance and you know it.
Some poster did say Denon amps tell you which cable you are using.
Maybe we should specify that as a part of testing equipment?

What Hans did was do some work showing zip cord speaker cables are not so perfectly fine as some people assume. Whether or not the result could be described as 'nuance' would be a matter of someone's personal opinion. If you like and respect the guy, then fiddling with cables is okay?? Otherwise, its audiophoolery? That's what I'm concerned about, how we judge people for believing cables matter.
