Silver plated copper

I doubt there's much measurable.

I will say that when I have tried them, I preferred pure copper. I felt the silver/copper cables took a long time before they sounded less harsh, and when they finally did, sounded no better than plain copper.

Of course, I'm probably nuts.

Best,
