Its conductor is solid Perfect-Surface Silver, AudioQuest's highest-quality metal, with no copper beneath. A Carbon-Based 6-Layer shield wraps it, and a 72-volt Dielectric-Bias System with an RF Trap sits on the cable.\u003c\/p\u003e\n\u003ch3 style=\"font-size:1.05em;margin:0.9em 0 0.25em 0;font-weight:600;\"\u003eA Solid Perfect-Surface Silver Conductor\u003c\/h3\u003e\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eAudioQuest says solid conductors prevent electrical and magnetic strand interaction. Perfect-Surface Silver, in its words, minimizes distortion caused by grain boundaries and maximizes linear dissipation of radio-frequency noise. Where the rest of the range plates copper with silver, Diamond is silver all the way through.\u003c\/p\u003e\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eHard-Cell Foam insulates the conductor. AudioQuest injects it with nitrogen to form air pockets, and says nitrogen neither absorbs nor releases signal energy. Its stiffness holds the conductor at a fixed spacing, which AudioQuest says produces a stable impedance character along the full length.\u003c\/p\u003e\n\u003ch2 style=\"font-size:1.25em;margin:1.4em 0 0.35em 0;font-weight:600;\"\u003eSix Shield Layers and a Biased Dielectric\u003c\/h2\u003e\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eAround the conductor sits Carbon-Based 6-Layer Noise-Dissipation, one layer more than Carbon and Coffee. AudioQuest says the alternating metal and carbon-loaded layers shield the shield, absorbing and reflecting most radio noise before it reaches the layer attached to ground.\u003c\/p\u003e\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eThe 72-volt Dielectric-Bias System adds an RF Trap on Diamond. The pack puts a steady charge on the insulation, which AudioQuest says improves wide-bandwidth dissipation of induced radio noise. The battery carries no load, so it lasts for years, and a button and light let you test it.\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;\"\u003eDiamond 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 silver end to end\u003c\/strong\u003e — Diamond's conductor is solid Perfect-Surface Silver and its plugs carry Hanging-Silver, so no copper sits in the signal path\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eYou are feeding a reference DAC\u003c\/strong\u003e — Diamond is the cable AudioQuest builds above Coffee, so it matches the top of a digital front end\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eYour rack is crowded with power supplies and WiFi\u003c\/strong\u003e — six shield layers and the RF Trap on the bias pack catch radio noise before it reaches the ground reference\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 gear has BNC or AES\/EBU sockets\u003c\/strong\u003e — an RCA plug will not fit them.
