This cable uses silver-coated copper covered with carbon and wrapped in a rubbery Hulliflex jacket.
I have had these cables running in my home theater system at my house for about 8 or 9 years now. I would say they have a minimum of 10,000 hours on them. They did a nice job in that application but I recently changed my home system and went with a different cable do to longer runs needed. They are not a good match with any of the gear I run in the showroom.
They are far too warm with an exaggerated bass for my gear (or my ears). Upper end detail and extension is very good.
They are in very good condition and banana terminated all around.
Make me an offer. Figure around $8 for shipping.
