The AudioQuest Diamond USB is a flagship digital interconnect engineered to deliver ultimate performance and timing precision in high-resolution USB audio applications. Designed to connect reference-grade music servers, streamers, or computers to digital-to-analog converters (DACs), the Diamond USB eliminates jitter, phase distortion, and strand-interaction noise for uncompressed dynamic clarity and soundstage depth.
Constructed with 100% Solid Perfect-Surface Silver (PSS) conductors, the cable provides an ultra-smooth metal surface that minimizes grain-boundary distortion. Signal conductors are biased with AudioQuest's patented 72V Dielectric-Bias System (DBS) featuring an integrated RF Trap to polarize insulation molecules and prevent frequency phase delays. Supported by nitrogen-injected Hard-Cell Foam (HCF) insulation and a Carbon-Based 3-Layer Noise-Dissipation System (NDS), the cable prevents radio-frequency interference (RFI) from compromising the receiving component's reference ground plane.
KEY FEATURES & PROPRIETARY TECHNOLOGIES
- Solid Perfect-Surface Silver (PSS) Conductors: Pure solid-silver conductors completely eliminate electrical and magnetic strand-to-strand interaction, offering maximum linear RF noise dissipation and phase accuracy.
- 72V Dielectric-Bias System (DBS) with RF Trap: Polarizes the dielectric with a strong electrostatic field to minimize energy storage and non-linear time delays while shielding against radio-frequency noise induction.
- Carbon-Based 3-Layer Noise-Dissipation System (NDS): Alternating layers of metal and carbon-loaded synthetics "shield the shield," absorbing and reflecting RFI before it can modulate the ground reference.
- Hard-Cell Foam (HCF) Insulation: Nitrogen-injected rigid foam dielectric creates inert air pockets to maintain strict signal-pair geometry and stable characteristic impedance.
- Direction-Controlled Conductors: Grain-oriented conductors are listening-tested to ensure induced RF noise is systematically drained away from sensitive audio circuitry.
