On top of that come solid conductors with 10% silver and carbon-based three-layer noise dissipation. It links computers, streamers and music servers to a DAC with a USB-B input and suits the majority of computer audio setups.\u003c\/p\u003e\n\u003cp\u003eEvery construction choice has a single purpose: keeping noise and timing errors away from the converter.\u003c\/p\u003e\n\u003ch3\u003eConductors\u003c\/h3\u003e\n\u003cp\u003eThe conductors are solid, hence free of the magnetic and electrical interaction among strands that generates distortion and jitter. The Long-Grain Copper (LGC) carries silver plating amounting to 10%: at digital signal frequencies the current flows almost only at the surface, which is where the silver does its work.\u003c\/p\u003e\n\u003ch3\u003e72V DBS, shielding and insulation\u003c\/h3\u003e\n\u003cp\u003eUnbiased insulation absorbs energy and gives it back in a non-linear way, delaying different frequencies by different amounts. The 72V DBS keeps the dielectric under tension and counters these timing errors; an RF Trap stops the DBS field elements inducing noise into the signal conductors. The Noise-Dissipation System alternates metal with carbon-loaded synthetic layers to halt radio interference short of the layer tied to ground. The Hard-Cell Foam insulation, expanded using nitrogen, stabilises geometry and impedance, and the conductors are Direction-Controlled.\u003c\/p\u003e\n\u003ch3\u003eTermination and lengths\u003c\/h3\u003e\n\u003cp\u003eCoffee USB comes in the USB-A \u0026gt; USB-B termination only: the USB-A plug goes to the source, the USB-B plug to the input of the DAC or amplifier.
