In a blind test, audiophiles couldn't tell the difference between audio signals sent through copper wire, a banana, or wet mud (www.tomshardware.com)

This is a really old test. There are forum posts of the same concept and some news articles with the test that are so old that they 404 now. An unshielded coat hanger is the most common. And yes, this is done frequently with analog signals. No, you can’t tell the difference.

It's a little confusing to me how it could be physically possible that there'd be no difference.

I'm not saying I think I could tell which is which, but surely they can't sound the same ? Or if they do, why do we even use copper, instead of just making cables out of the cheapest random conductive substance available ? Is copper just that substance ?
