Query: Excellent quality

Works great for my speakers (max run was 36 feet). Sound on my Polk monitor50's is flawless.- Was actually a little over 100 feet- White line on positive wire so you can tell them apartStripping can be a little tricky, but no harder than any other wire I have used. If you don't have a wire-stripper, even a razor blade or steak knife could do the trick on these.Not much more to say, it's speaker wire. It's top-quality. There's no reason to buy the pricier stuff, it won't sound any better than this.
