AudioQuest Diamond USB-A to USB-C High-Definition Audio Cable
Frequently Bought Together
Product Overview & Specifications
The AudioQuest Diamond USB 3.0 (A to Micro) is a flagship digital interconnect designed for reference-grade audio playback, external drive data transfer, and digital audio streaming from USB 3.0 hosts to compatible DACs, digital converters, or high-performance audio storage drives. Engineered to eliminate timing jitter, phase delays, and strand-interaction noise, the Diamond USB 3.0 delivers exceptional dynamic clarity, detail retrieval, and soundstage depth.
Constructed with 100% Solid Perfect-Surface Silver (PSS) conductors, the cable provides an ultra-smooth metal surface to optimize high-frequency digital transmission. Signal integrity is maintained using AudioQuest's patented 72V Dielectric-Bias System (DBS) with an integrated RF Trap to polarize insulation molecules and prevent non-linear 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 receiving electronics.
