I can only have an educated guess as to how it'd (unpure wires) affect the audio. But it's nice to know that it's not highly important what material it is (by that I mean either silver or copper) :D.
I've read that there is a noticeable difference when going to balanced. Since I'm going the crack route, I could see if there's a way to make the crack a balanced system or just settle down with making a basic DIY cable with 1/4 " connector.
