Might just be a difference in terminology, here. I checked with someone who does a lot of reworking of Hero and other Kimber Kables. He says there is no shield in the usual sense--no braided shield. I know that the common (ground) wires braided in (or perhaps otherwise included) serve much of the noise-cancelling function of a conventional shield. Your response, saying that the ground wires are wrapped (you didn't say braided) may be new information for me. I was imagining that Kimber's terminology of "gyro-quadratic" meant a four-strand braid--like maybe a "French braid" type of construction, perhaps like the Corpse Cables brand uses. After reading your last post I'm not sure HERO is braided at all. Not that it matters terribly; they sound great, no matter how they are made. But it does arouse my curiosity as a former Electronics and Space field engineer.
