Hi, Is anyone familiar with this concept? Here is a phono cable. I thought the thin wire was a ground, but it's actually a shunt. It's supposed to help with RF noise, I think. It says this: "Shunts are attached to floating shields. The Shunts attach to the ground post of your phono preamp. PLEASE NOTE: The shield shunt does not provide a ground connection." I've never seen this on any other cable. Have you? Thanks!
