Wire, is not just wire.
You are right. Some are silver, most are copper and a few some other material, perhaps magnet wire.
The outer material is mostly different, at least the colors, etc.
As to your comparison and the setup, perhaps the setup is sensitive to some wire parameter. We don't know without in depth inspection. As to your listening protocol, totally flawed so it has no real value, unfortunately.
Also, you need to kn ow about the workings of human bias, the brain and perception, critical to understand.
Class site you have here. I'm a newbie. Have I broken some secret taboo?
Moderator....feel free to delete my login. This place doesn't meet my personal standards, so I'm gone.
Not sure what your standards are, what your expectations are. No, you did not break any taboo. Actually, this site is very accommodating and your post was not deleted as some sites tend to do.
But, most here tend to approach testable claims in an objective manner.
So, if you stick around you may learn a few things about audio, if that is your goal.
