AudioQuest Diamond USB-C > A High-Definition Digital Audio CableMULTI LAYER CARBON BASED NOISE AND CROSSTALK DISSIPATION SYSTEM This cable's negative conductors are covered with partially conductive Carbon Loaded Polyethylene. This remarkable material reduces radio frequency garbage being fed back into the amplifier. The sonic benefit is exactly the same reduction in "hash" and improved dimensionality that comes whenever RF interference is reduced in an audio circuit. In addition, a carbon layer damps interaction
