Atlas Cables first ‘high-end’ USB cable, featuring the Grun Coherent Earthing System,
designed to maximise performance from file-based audio sources.

  • Connector Type: USB-A to USB-B / USB-A to USB micro-B
  • Conductor Material: OCC Copper data & power
  • Dielectric Material: PEF (Foamed Polyethylene)
  • Screen: OFC 85%
  • Shielding: Al Mylar™ (100%), OFC (90%) with Grun grounding connector
  • Construction: Multicore

Wide bandwidth CAT6A compliant high-speed OFC solid-core cable engineered for precisely-defined digital signal transmission.

Digital theory suggests that data is nothing more than a sequence of ‘ones & zeros’ and all that’s required of a cable is to transfer data around the network. While that’s essentially true, it emerges as an overly simplistic perspective when considering high-resolution low-level signals.

While the OSI 7 layer Ethernet protocol specification covers packet switching, error correction, timing and end-to-end transmission, as in any audio cable there are areas where the selected materials, construction techniques, connectors, and termination methods can all audibly impact the signal integrity. All Atlas streaming Ethernet cables are tested to and certificated to be compliant to the highest ISO/TIA standards for patch cords.

Atlas streaming cables benefit from the expertise and experience gained with the continuing development and evolution of our high-speed video and USB audio cables.

Our optimised insulation displacement solder-free construction methods produce a continuous high-integrity fully-shielded signal path avoiding the breaks in material continuity which degrade ultimate fidelity. We utilise high-purity solid-core OFC conductors with stable low-loss PEF dielectric, a zinc die-cast RJ45 connector, in a precision-calibrated production process which pays particular attention to maintaining the balance between tight twist ratios and symmetrical twist patterns, minimising signal errors. Fewer errors means the correction circuitry in the receiving device has less work to do - a high level of error correction can itself introduce more noise – extracting and processing the data.

Our Mavros cable features our Grun Coherent Earthing System as an achromatic part of maximising performance from Ethernet sources, by draining this “noise”’ away to an ‘independent’ ground.

The Grun connection can be made via the supplied Grun lead with spade tag (connect to your amplifier’s chassis or ground post), or for optimum performance, the optional Grun mains adaptor connected to a power socket or mains distribution block.

This ‘noise’ doesn’t directly present as ‘hash’ or interference, but impacts on a DAC’s clock accuracy and error correction circuitry, compromising fidelity – the practical, audible result is a cleaner audio signal with a wider dynamic range and less of the ‘glare’ which typically results from high levels of unwanted ‘energy’ in the signal data.
