The solid Long-Grain Copper (LGC) conductors eliminate strand-interaction distortion. Black Labs solid Long-Grain Copper allows a smoother and clearer sound than cables using regular OFHC (Oxygen-Free High-Conductivity) copper. LGC has fewer oxides within the conducting material less impurities less grain boundaries and definitively better performance. Any solid material adjacent to a conductor is actually part of an imperfect circuit. Black Lab uses air-filled foamed-polyethylene insulation on both conductors because air absorbs next to no energy and polyethylene is low-loss and has a benign distortion profile. Thanks to all the air in foamed-PE, it causes much less of the out-of-focus effect common to other materials. Metal-layer Noise-Dissipation System (NDS) prevents captured RF Interference from modulating the equipment’s ground reference. It prevents a significant amount of RFI from reaching the equipment’s ground plane. Symmetrical coax geometry with identical conductors prevent the shield being used as an inferior audio conductor. Cold-welded and gold-plated terminations plug design allows for a connection devoid of solder which is a common source of distortion. Because the ground shells are stamped instead of machined the metal can be chosen for low distortion instead of machinability.
