AudioQuest Diamond USB-C to Micro B High-Definition Audio Cable

The AudioQuest Diamond USB-C to B Digital Audio Cable is crafted for discerning audiophiles who require a high-end USB-C to USB-B digital path. It combines ultra-pure conductor materials, multi-layer noise control, dielectric bias technology, and precision engineering to deliver a pristine, low-jitter signal that reveals maximum musical detail and transparency.

Supreme Conductor Purity and Signal Integrity

This cable employs solid Perfect-Surface Silver (PSS) conductors—meaning the core is pure silver with an ultra-refined surface polish to minimize grain boundary distortion. Because digital audio signals often travel along the conductor’s surface at high frequencies, this purity helps maintain clarity and reduce resistive loss. The solid-core design avoids the distortions associated with stranded wire.

Multi-Layer Noise Dissipation Design

To protect the digital signal from external interference, the Diamond USB-C to B uses a multi-layer Noise-Dissipation System (NDS) combining alternating layers of carbon and conductive materials. This scheme absorbs, reflects, and diverts electromagnetic and radio-frequency noise before it can corrupt the signal or ground reference. The conductors are also directionally optimized so induced noise is guided away from sensitive endpoints.

Dielectric Bias and Insulation Strategy

The cable includes a 72 V Dielectric-Bias System (DBS) that applies a consistent electrostatic field across the insulating medium to reduce nonlinear dielectric behavior. This helps minimize memory effects and distortions in the insulation. The insulation itself consists of rigid nitrogen-injected foam (or similar air-rich foam) that ensures minimal dielectric absorption and stable geometry. This design supports consistent conductor spacing and impedance, reducing timing distortions across the cable.
