Beginner Question

I was demoing speakers last weekend and at both shops they used a speaker cable that was about a 2-3 inch tall ribbon. It was bright silver, almost chrome looking. It has multiple thin wires side by side. Does anyone know the brand or types? I should of asked but was focused on the speakers, but thought it interesting that both shops used the same cable. BTW, listed to Wilson Audio Sabrina X and the Monitor Audio Platinum 300 II. I thought both sounded different but great in their own way.
