Audioquest Pearl USB-A>USB-B - 5 m

Description

Precision Engineering for Uncompromised Audio
The AudioQuest Pearl USB High-Definition Audio Cable is purpose-built for high-fidelity signal transmission between digital audio sources and DACs. Designed for both professional and home audio applications, this cable integrates advanced materials and engineering to maintain signal integrity across all frequencies. Every component, from the conductor core to the outer shielding, serves a distinct role in minimizing noise, distortion, and energy loss.

Solid Long-Grain Copper Conductors
At the core of the AudioQuest Pearl USB are Solid Long-Grain Copper (LGC) conductors that deliver exceptional clarity and tonal accuracy. Unlike stranded conductors, solid cores eliminate strand interaction—a primary cause of phase distortion and signal degradation. The high-purity copper used in LGC offers fewer grain boundaries, reducing micro-level impurities and oxide formation. This results in a smoother electrical path, enabling precise signal flow and improved sonic detail across all playback levels.

Metal-Layer Noise-Dissipation Technology
AudioQuest’s proprietary Metal-Layer Noise-Dissipation system protects the signal path from high-frequency interference. While traditional shield systems direct captured noise into the component ground, AudioQuest’s design effectively "shields the shield" by absorbing and reflecting radio-frequency interference (RFI) before it reaches the ground plane. This prevents modulation distortion, preserving low-level detail and maintaining the integrity of the “reference” ground—critical for maintaining tonal accuracy in digital playback.

Hard-Cell Foam Insulation for Dimensional Accuracy
The Hard-Cell Foam (HCF) insulation layer provides structural stability to ensure precise conductor geometry along the cable’s length. Formed from nitrogen-injected material, the foam creates high air content pockets that minimize energy absorption. This design prevents stored energy from re-entering the signal path, reducing time-based distortion and delivering cleaner, more transparent sound. The consistent dielectric spacing also stabilizes impedance characteristics, further enhancing signal fidelity.

Direction-Controlled Conductor Design
Each conductor in the Pearl USB cable is direction-controlled to guide signal flow and drain away radio-frequency noise. By evaluating the directional properties of every metal batch, AudioQuest ensures optimal noise dissipation and consistent performance. Clear directional markings on each connector assist with proper installation, ensuring the signal path operates as intended. This advanced system supports AudioQuest’s multifaceted Noise-Dissipation Technology, guaranteeing performance that exceeds typical USB cable standards.
