Ailsa Ultra L RCA Grun
Advanced OCC copper interconnect.

Wide-bandwidth balanced core RCA interconnect cable, the Ultra Latik Grun version utilises our new ‘balanced core’ geometry for a performance which sets a new standard at this level.
Conceived as a ‘turbo-charged’ version of the very well-reviewed Ailsa Achromatic X RCA, the Ultra Grun version seeks to maximise the performance potential inherent in the Ailsa topology. Cable configuration is our new ‘balanced core’ geometry. Connectors are upgraded to custom-designed low-mass Ultra L RCA plugs. It incorporates our precision dd (dual-drain) system and Atlas’ Grun Coherent Earthing System connector (basic adapter included).
The Ultra L (Latik) RCA plug benefits from an innovative and extremely stable non-conductive 3D-printed geometric lattice structure.
We based our ‘dd’ (dual-drain) configuration on techniques originally developed for our top-of-the-range Mavros and Asimi interconnects. 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.
Typically, screened cables suffer from screen distortion when prepared for production. Cutting and twisting the screening braid has a measurable impact, effectively changing the impedance and, therefore, the cable's performance. The benefits are maintaining a constant low impedance load to the plug and total 360° screening against noise and signal degradation caused by RFI (Radio Frequency Interference).
The result is an inviting, open, natural sound which we think, like the Ailsa Achromatic X RCA, defines a new performance standard at its price point.
