Audiolund USB A-B Cable ~ Xtreme Series
Key Features
- Constructed with 4 × 16 AWG Duelund tinned copper conductors
- USB Type-A to Type-B configuration
- Multiple types and layers of shielding materials help reduce noise and RFI/EMI interference
- Unique damping construction incorporates various anti-vibration and damping materials to help suppress and isolate unwanted vibration
- Standard length: 1.0 m, with other lengths available
- Available in Standard USB or Dual-Headed USB configurations
Standard USB version: Features one USB-A connector and one USB-B connector, without a separate 5V DC power supply connection
Dual-headed USB version: Features two USB-A connectors and one USB-B connector, allowing the 5V DC power supply to be separated from the audio source. One USB-A connector connects to the audio source, while the second connects to an external 5V DC power supply.

Designed Specifically for High-End Audio
Typical USB cables use conductors ranging from approximately 20 AWG to 28 AWG. The Xtreme Series USB Cable uses substantially larger 16 AWG conductors, placing sound quality and audio performance at the forefront of its design.
The Xtreme Series is developed specifically for use with high-end audio components such as streamers, media players, DDCs, and DACs. Due to its specialized construction, it is intended for audio applications and is not recommended for general networking or computing use.
Testing and Compatibility
Rather than relying solely on laboratory measurements, Audiolund evaluates its USB cables through extensive listening and compatibility testing across multiple high-end audio systems, including various combinations of streamers, transports, DDCs, and DACs.
Across the systems evaluated, the Xtreme Series has demonstrated stable signal transmission without observed signal errors and has performed reliably with a wide range of audiophile system configurations.
Sound Characteristics
The Xtreme Series USB Cable shares the core sonic characteristics of the Signature Series, while incorporating a higher-grade Duelund conductor configuration to further enhance its overall musical presentation.
Its character reflects the distinctive qualities associated with Duelund tinned copper conductors and vintage Western Electric-inspired sound, presenting music with a fuller body, greater warmth, natural tonal balance, and an engaging musical flow.
The use of 16 AWG Duelund conductors contributes to a richer and more substantial presentation, with increased body and warmth while preserving musical coherence and naturalness.
The Xtreme Series USB Cable is designed for audiophiles seeking the highest level of musical performance from Audiolund’s Duelund-based USB cable designs.
Audiolund Listening Notes
With its all-16 AWG Duelund conductor construction, the Xtreme Series USB Cable retains the distinctive tonal character associated with Duelund tinned copper while delivering a fuller-bodied, warmer, and more substantial presentation.

USB A-B Plugs Orientation

Audiolund cables feature a relatively thick and substantial construction. While the cable can be bent for installation, its construction makes twisting more difficult. Correct connector orientation is therefore important for easier installation and to minimize unnecessary torsional stress on the cable and connectors.
The USB A-B connectors are supplied in our standard orientation. However, the ideal orientation may vary depending on the placement and configuration of your equipment, for example:
- Top to bottom
- Left to right
- Right to left
To ensure the correct connector orientation for your system, please provide a clear photo of the rear of your equipment showing the USB A-B connection points when placing your order.

Most Audiolund cables employ multi-core constructions with multiple conductor combinations, and therefore require an extended run-in period before reaching their intended performance.
OCC Silver conductors use relatively thick solid-core wire and typically require a longer run-in period than Duelund tinned copper, which uses multiple parallel thin strands.
General Run-In Guidelines
- Most Audiolund cables: approximately 100–200 hours
- Xtreme Series: approximately 200–400 hours
These figures should be regarded as general guidelines, as actual run-in time may vary depending on the cable design, system, and usage conditions.
