Atlas Grun Ultra USB Interconnect. Our new Reference.

Now at True Audiophile cable products

We literally spent 3 months testing this cable line both in-house and with clients. The initial claims made us suspicious. After all the feedback we gave in. These are remarkable cables, especially at their price. Feel confident that your hard-earned audio dollars were well spent -- True Audiophile 

We carry the complete line of Atlas Cables. If you don't see it on our site, just inquire.

An OCC copper USB cable specifically developed to meet the requirements of USB as a high-end audio interface.

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

It’s become evident in recent times that noise is frequently a major issue limiting the performance of file-based replay via USB connections.

Computers and server streamers are notoriously problematic in this respect, although there exists a new generation of dedicated music servers designed with an emphasis on designing good sounding USB outputs by minimizing their electrical noise leakage.

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, compromising 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 minimized.

It’s become evident that hardware alone can’t fully address the issue.

Atlas Mavros USB utilises our Grun Coherent Earthing System as an integral part of maximizing performance from USB sources, by draining this 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.

There are, of course, additional critical factors in designing a reference-class USB cable. Atlas set out to minimize reflective losses in high-speed USB cables by improved termination methodology, higher purity conductors (OCC copper) and improved screening.

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

Mavros Grun USB is available in USB type A/B and A/B micro versions and various lengths.

NOTE: For best performance you will need an Atlas NEMA ground plug.
