Ailsa Duo Ultra L RCA Grun
Advanced OCC copper interconnect.

Wide-bandwidth solid-core RCA interconnect cable utilising our new 'Duo' independent dual-drain screen topology, a further refinement of our proven 'dd' dual-drain system.
Designed to overcome the shortcomings of conventional coaxial cables, the Ailsa Duo Ultra L RCA features two separate, independently screened solid-core OCC copper conductors for 'hot (+) and 'cold‘ (-) connections, enhancing rejection of unwanted signal-degrading ‘noise.’ Solid-core offers significant improvement over multi-strand conductors, with lower distortion and greater consistency in performance.
Connectors are our acclaimed, low-mass Ultra L (Latik) RCA plug, which benefits from an innovative and extremely stable non-conductive 3D-printed geometric lattice structure, designed to have minimal impact on the delicate signal. Pins are of the same grade OCC copper as the conductors, which, in tandem with our solder-free cold-weld connection method, ensures excellent signal continuity.
Combined with a precision-twisted assembly – further increasing rejection of RF and EM interference – we’ve created a cable with a distinctive appearance, and we believe, clear, easily demonstrable performance gains with more than a hint of the coherence and tonal accuracy of our 'High End' Mavros and Arran products.
Listening to this latest generation ‘rebooted’ Ailsa reveals a neutral, detailed but engaging presentation without artifice or exaggeration, offering fresh insight into both new and familiar music.
Performance – particularly with regard to increaing dynamic range by lowering the system noise-floor – is further enhanced by Atlas’ Grun Coherent Earthing System (Grun lead & spade adapter included).
