I never said there was silver magic, nor did I imply it. That is an erroneous and rather offensive stereotype that I don’t appreciate.
Correct, but you said that Silver conducts 7% faster than copper.
I understand that silver conducts 7% faster than copper
And also that the teflon keeps it from overheating.
Both those statements are erroneous.
It is also a fact that Silver is touted as having magical qualities by many manufacturers that sell it. Gold is actually 3rd behind silver and then copper in conductivity, but it also has a magical allure.
I don’t deny my lack of knowledge. However, I have decades of experience. You may see that as baseless testimony with no "facts" to back it up, but no one will have those facts
it is not your lack of knowledge that is the problem, it is that much of this gear is marketed with magical properties and stories which are laden in golden eared testimonials. Some/most cables do not even list the specs! At least Kimber provides some specs for the speaker cables (4TC and 13TC at least), so they are up the list a ways in comparison.
Without some provable facts it is difficult to understand whether they work or what they do. I would usually prefer to put the funds into a piece of gear that is more immune to needing a cable in the first place.
If the manufacturer says that “brand-X” cable is what they recommend than that is at least a good start.
Without that we are left with listening tests, and experience.
There are no tools for measuring sound quality except the human ear and that tool is subjective.
Ask your EE friend if he could measure the voltage of the power supply output. If so, then he would then have a way to show whether or not it was dropping down and a “faster cable” might help fill it better.
See what he says.
if the power supply output is rock solid, then I cannot imagine any way that a cable could help… but more noise would be worse.
He will know what is means, and could give you some insight.
