Review on High Performance 12 AWG Oxygen-Free Speaker Wire - 25ft - Polarized by Michael Willis

This is not pure copper. I bought it because the answers and reviews said it was pure copper. It is not. Cutting the wire you can clearly see that the "copper" wire is silver with a copper coating. I would say it's copper-aluminum. I definitely received the product pictured in the Revain description. He's got a role and stuff. But it is NOT copper. I tried to take a good photo but it was the best I could do. I'm only including this photo so people pay attention to the rating.
