USB Cables

The AudioQuest Diamond USB is the flagship model in AudioQuest's USB cable lineup. It is designed for high-end audiophile systems where the goal is to minimize the "digital glare" and timing errors (jitter) often associated with computer-based audio.

Product description

Diamond USB features high-purity 100% Silver conductors and Carbon-Based Noise-Dissipation for optimal dissipation of radio-frequency noise.

Key Technical Features

AudioQuest incorporates several proprietary technologies into the Diamond to justify its "reference" status.

  • 100% Perfect-Surface Silver (PSS) Conductors: Unlike lower models that use silver-plated copper, the Diamond uses solid, high-purity silver. This is intended to eliminate "strand interaction" (a source of distortion) and provide a smoother surface for signal travel.
  • 72V Dielectric-Bias System (DBS): You will notice a small battery pack attached to the cable. This creates a strong, stable electrostatic field that "polarizes" the insulation. The goal is to minimize energy storage in the dielectric, which AudioQuest claims reduces non-linear time delays.
  • Carbon-Based 3-Layer Noise-Dissipation (NDS): This uses alternating layers of metal and carbon-loaded synthetics to "shield the shield." It is designed to prevent RFI (Radio Frequency Interference) from reaching the equipment's ground plane.
  • Hard-Cell Foam Insulation: Nitrogen-injected foam creates air pockets; because air absorbs almost no energy, it helps maintain the signal’s integrity and the cable's physical geometry.
