Dover, AntiCables make several different cables for sale at different price points, and moreover they have recently revised their shielding for more coils per unit length. So which of their products are you denigrating here? I’m using their latest and highest end cable which contains separate and equal silver/gold conductors for hot and ground, respectively, (2 pair in each direction) with an entirely separate copper coil for shielding. RCA plugs are the best of the KLE product line, which I happen to like. I don’t perseverate too much on cables, although I do believe they make a big difference. I needed one 22-foot length cable to run from my Steelhead to the built-in amplifier on a Beveridge speaker; the other channel needs only about 12 feet.
Where and on what gear have you auditioned whatever AntiCable you're referring to? For signal carrying, "thicker" is not necessarily better (in my direct experience, it's usually worse), and "thick" dielectric is almost always not desireable, but this is Off Topic. Let’s not get into another digression about whose cables sound best; I am only trying to help out the OP to think about the trade-off between shielding and capacitance.. You or anyone else can insert any other brand with low capacitance and effective shielding here. If you want, start another thread on cables.
Finally, I don’t know what you mean by your last sentence: "Generalizations are dangerous...." Where did I generalize? I think you would agree that shielding per se adds to capacitance. And I did measure capacitance myself, in order compare the AntiCables to the cables I replaced, as far as checking specs (see above). Funnily, you say yourself above that the generalized AntiCable has a lower C per meter than whatever it is you use. QED
