Detailed Description

Impedance-Controlled Data Lane

The QED Reference High Resolution USB employs a 24 AWG, 99.999% oxygen-free copper twisted pair with low-permittivity, foamed-polyethylene dielectrics. This arrangement is uniformly bound by an aluminium/mylar wrap, ensuring strict impedance control at 90 Ω ± 5%. The design minimizes jitter and timing errors, exceeding USB 2.0 standards and ensuring a smooth, enjoyable listening experience.

Clean Path Audio™ Technology

To combat potential sound quality degradation caused by USB power noise, QED integrates a double-layer shield with a 100% aluminium/mylar wrap and shield braid. This design electrically isolates data lanes, preserving the purity of the audio signal without deviating from the USB specification.

Ferrite Insulation™ Technology

A proprietary Zn/Mn floating ferrite jacket is embedded within the cable’s inner layer, absorbing high-frequency noise both internally and externally. This unique insulation minimizes jitter, creating a quieter electrical environment and enhancing overall sound fidelity.

Ultra-low Jitter Geometry

The cable's geometry ensures a significant reduction in jitter, as verified by eye pattern analysis. This advancement halts signal distortion caused by jitter, improving audio clarity and reducing listener fatigue. The result is a more relaxed and immersive listening session, perfect for high-resolution audio applications.

High-Resolution Audio Optimization

Designed for demanding audio applications, the cable’s superior timing performance and low jitter ensure distortion-free playback of very high-resolution audio formats like 32 bit/1.536 MHz generated by HQ Player or other upsamplers. This precise data transfer delivers a richer and more enjoyable listening experience for discerning audiophiles.
