Its conductors are Long-Grain Copper with 10% silver plating, double that of Carbon. It keeps the Carbon-Based 3-Layer shield and Hard-Cell Foam, and adds a 72-volt Dielectric-Bias System pack on the cable.\u003c\/p\u003e\n\u003ch3 style=\"font-size:1.05em;margin:0.9em 0 0.25em 0;font-weight:600;\"\u003eLong-Grain Copper With 10% Silver Plating\u003c\/h3\u003e\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eAudioQuest says a USB signal is so high in frequency that it travels almost entirely on the surface of the conductor. The 10% silver layer on Coffee is the thickest AudioQuest applies to copper. Above it sits only Diamond, in solid silver. Every conductor is direction-controlled.\u003c\/p\u003e\n\u003ch2 style=\"font-size:1.25em;margin:1.4em 0 0.35em 0;font-weight:600;\"\u003eA 72-Volt Bias on the Insulation\u003c\/h2\u003e\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eThe Dielectric-Bias System is a small battery pack on the cable. AudioQuest says it \"saturates and polarizes insulation, allowing clear, dynamic sound against a quiet 'black' background.\" The batteries see no load, so they last for years. A button and light let you test them.\u003c\/p\u003e\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eAround the pair sits Carbon-Based 3-Layer Noise-Dissipation. Metal and carbon-loaded layers alternate three deep, and AudioQuest says they catch most radio noise before it reaches the layer tied to ground. Coffee is a USB 2.0 cable rated to 480 megabits per second.\u003c\/p\u003e\n\u003ch3 style=\"font-size:1.05em;margin:0.9em 0 0.25em 0;font-weight:600;\"\u003eThe USB-A and USB-B Plugs, Explained\u003c\/h3\u003e\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eCoffee ends in a flat USB-A plug for the computer end and a square USB-B plug for the DAC end.
