This speaker cable is legal. I've used it to bi-amp the front speakers and they've never sounded better. It's a little tricky to strip the ends of the inner wires, but honestly I think that's a good thing as it means the insulation is snug around the wires. If, like me, you're thinking about using this cable for bi-wiring or bi-amping, stop thinking about it and buy it! You'll be glad you did.
