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.
