Speaker cable

From reading the Amazon description, both conductors a pure copper. The insulation on the negative appears to be white, the positive looks like it has clear insulation.

Aluminium is my favorite one.

Really? Aluminum for speaker cables? 🤦‍♂️

More audiophile nonsense

I remember decades ago buying spools of speaker cable at Radio Shack . One leg had a silver look. Strictly to identify + and - . Don't think it's any more than that.

@ron_hartman .. but marking the cable, instead of marking the cover is a strange way of identifying it, would not you think? And I wonder if this indeed is a copper, and not something else as the substitute. Nevermind the lamp cord, but this is the cable for the entirely different application altogether.
