Mavros Grun USB is the first truly high-end USB cable from Atlas Cables, featuring their renouned Grun Coherent Earthing System, and available in Type A/B, and A/B micro connector versions. Mavros Grun USB is designed to maximise performance from all file-based audio sources, hugely improving any streaming or digital audio system.

It is evident that noise is frequently a major issue which limits the performance of file-based replay via USB connections.

This noise is typically not directly audible as hiss or interference, but it does have an impact on a DAC’s clock accuracy and error correction circuitry, which in turn compromises tonal accuracy and dynamic range. While it’s not easy to hear while present, it becomes easy to hear the difference when it’s removed or minimised. Hardware alone cannot fully address the issue.

Mavros USB utilises the Atlas Grun Coherent Earthing System as an integral part of maximising performance from USB sources, by draining noise away to an independent ground. The Grun connection can be made via the supplied Grun lead with optional spade tag (connect to your amplifier’s chassis or earth terminal), or for optimum performance, via a Grun mains adaptor connected to a power socket or mains block.

Other factors in designing a reference class USB cable, such as minimising reflective losses in high speed USB cables by improved termination methodology, higher purity conductors (OCC copper) and improved screening.

Construction of Mavros USB is meticulous, with particular attention paid to minimising the effect of impedance variations, dielectric losses, intra-pair skew and skin-effect issues. In combination, these elements typically add jitter, which is generally regarded as the primary performance killer in digital audio systems.

Luxe Finish Options

Atlas Cables offer a range of special Luxe finish options for this premium USB audio cable. Four standard leather colours plus optional finishes available in contrasting or self-colour stitching options. Bespoke colour matching options (RAL or Pantone) are also available.

Please contact Audio Sanctuary to discuss your requirements if you would like to pursue the Luxe options.


  • USB Type A Connector - Precision moulded, 360° screened USB Type A connector with superior transmission & reception properties, maintaining the termination characteristic impedance.
  • OCC Copper Conductor - (OCC) Ohno Continuous Casting copper was developed based on research that sound quality was related to the quality of copper and the processing used during cable manufacture.
  • PEF (Foamed Polyethylene) Dielectric - The foaming process uses a blowing agent, of which there are two types. Atlas use the gas-foamed method which creates a more inert, consistent and higher quality product.
  • Multi-Core Construction - Optimised conductors (one for signal path, the other for power) enclosed within a non-conducting screen. The configuration minimises noise and interference.
  • Grun Coherent Earthing System - An independent system earth which eliminates low-level RFI, EMI and noise on the signal ground. Read more...
