Atlas Cables Arran Ultra L RCA Grun

State-of-the-art OCC copper interconnect.

A new generation. Technically and sonically sophisticated cables created to complement the world’s finest stereo components, the Arran family represents Atlas’ most accomplished OCC copper audio cables to date.

The Arran Ultra L RCA Grun is our top-of-the-range OCC copper interconnect, created as a true ‘no compromise’ design to complement the performance of the finest audio systems.

Arran uses the highest quality ‘6N’ (99.99997% purity) elongated-crystal copper manufactured using the OCC (Ohno Continuous Casting) process, ensuring the signal follows a faster, cleaner and more direct path. The cable utilises a pair of conductors comprising six solid OCC strands surrounding a seventh central core, tension-wrapped in a microporous PTFE dielectric. 

An advanced continuous screen with a copper shielding braid ensures minimal RF interference and noise susceptibility. The unique 3D-printed liner within the Ultra L plug reduces the influence of the connector itself to extremely low levels.

The cable also incorporates our precision dd (dual-drain) system, where twin symmetrical drain wires connect the screen to the cable return/plug interface, allowing cable termination without distorting, twisting or mechanically stressing the precision-laid screen, along with Atlas’ Grun Coherent Earthing System (Grun lead & spade adapter included).

The result is a beautifully balanced, temporally coherent, natural sound with a vanishingly low noise floor and deceptively wide dynamic range. Music gains both time and space; listening to music via Arran has a pervasive sense of calm; an extremely high level of detail is apparent, but only as part of a coherent whole, without any sense of artificial emphasis or exaggeration.

We designed every single aspect of Arran to minimise any audible signature.

Remove the influence of the cable itself, and only the music remains.
