The conductor is made of advanced silver-coated copper wire, and has high conductivity, good signal transmission and low loss. These cables use highly pure 99.997% "OFC" Oxygen free copper. These are true 75 ohm cables Using foamed PE (FOAMED POLYETHYLENE, widely regarded as the superior dialectric material). Distortion arising from unmatched impedances are eliminated using thick, low capacitance, 75 ohm cable. These cables are double shielded with 80/0.10mm highly pure OFC braiding. The adjustable locking connectors--"RCA" plugs employ 24K gold-plated copper to lower contact resistance.
