Its solid Long-Grain Copper conductor carries a 10% silver plating, double that of Carbon. It keeps the Carbon-Based 5-Layer shield 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;\"\u003eSolid 10% Silver Over Long-Grain Copper\u003c\/h3\u003e\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eAudioQuest says a digital signal travels almost exclusively on the surface of the conductor, so it plates the copper with increasingly thick silver as the range climbs. Coffee's 10% layer is the thickest AudioQuest applies to copper. Above it sits only Diamond, in solid silver.\u003c\/p\u003e\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eThe conductor is solid, which AudioQuest says prevents the strand interaction that causes dynamic distortion. Hard-Cell Foam, injected with nitrogen, holds it at a fixed spacing so the impedance stays stable, and AudioQuest says nitrogen stores no signal energy to release later as distortion.\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 insulation is also a dielectric that can act like a shunt filter, and that biasing it minimizes dielectric noise and linearizes the filter, improving wide-bandwidth dissipation of induced radio noise. The batteries see no load.\u003c\/p\u003e\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eAround the conductor sits Carbon-Based 5-Layer Noise-Dissipation. AudioQuest says alternating layers of metal and carbon-loaded synthetics shield the shield, absorbing and reflecting most radio noise before it reaches the layer attached to ground. That keeps the reference plane cleaner.\u003c\/p\u003e\n\u003ch3 style=\"font-size:1.05em;margin:0.9em 0 0.25em 0;font-weight:600;\"\u003eThe RCA Plugs, Explained\u003c\/h3\u003e\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eCoffee ends in a cold-welded RCA plug at each end, plated with Hanging-Silver directly over pure Red Copper. RCA is the single-pin plug on the coaxial digital output of most CD players, streamers and DACs. AudioQuest joins plug to wire under high pressure with no solder, which it calls a common source of distortion.\u003c\/p\u003e\n\u003ch2 style=\"font-size:1.25em;margin:1.4em 0 0.35em 0;font-weight:600;\"\u003eWho Is This Digital Cable Best For?\u003c\/h2\u003e\n\u003cul style=\"margin:0 0 0.9em 0;padding-left:1.4em;line-height:1.6;\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eYou want the most silver on copper AudioQuest makes\u003c\/strong\u003e — Coffee's 10% plating is double Carbon's, so the surface the signal rides on is as close to solid silver as the copper range gets\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eYou want the bias system without buying Diamond\u003c\/strong\u003e — Coffee is the least expensive AudioQuest coax with the 72-volt pack, so the technology arrives here\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eYour CD player or streamer has a coaxial output\u003c\/strong\u003e — the RCA plugs fit the orange coax socket on most sources and DACs, so no adapter is needed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eYour rack is crowded with power supplies and WiFi\u003c\/strong\u003e — the five-layer carbon shield soaks up radio noise before it reaches the ground reference, so the DAC sees a cleaner signal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eYour gear has BNC or AES\/EBU sockets\u003c\/strong\u003e — an RCA plug will not fit them.
