The Arran Transpose Speaker is an advanced wide-bandwidth loudspeaker cable which, as Atlas’ most accomplished OCC copper cables to date, represents the pinnacle of our design & manufacturing expertise.

The Arran Speaker Grun is an technically and sonically sophisticated wide-bandwidth OCC loudspeaker cable representing the pinnacle of our design & manufacturing expertise.

The Arran family is positioned between our acclaimed Mavros and Asimi ranges and represents Atlas’ most accomplished OCC copper audio cables to date. The Arran Speaker Grun features high purity ‘6N’ (99.99997% purity) elongated crystal copper manufactured using the OCC (Ohno Continuous Casting) process. Six solid OCC copper conductors are meticulously encased within a graduated dielectric with formed air voids. The cotton spiral and tension-controlled wrapped PTFE is further optimised by the SSG (super stabilised geometry) layer which maintains constant cable symmetry over its length.

For maximum flexibility as your system configuration changes, termination is via our cold-weld Transpose Modular Termination System. In a cold-weld (solder-free) connection, the metal of the connector plug and the conductor are squeezed together under a precision-calibrated pressure to form a robust, consistent, air-tight metal-to-metal contact with no deformation of the cable dielectric. The result is a smooth, uninterrupted signal path which behaves as one continuous entity.

Results with our Arran cables are further enhanced by the configuration of our Grun Coherent Ground System, cables and adapter options, acclaimed by the world’s specialist audio press as a key element in achieving the highest possible level of system performance. A set of Grun leads and spade adapters are supplied with each cable as standard; ultimate performance can be attained via our Grun mains adapters, which can be used with up to four Grun cables.

This cable is fitted as standard with the Transpose Modular Termination System, which allows easy switching between Z (Gold or Silver 4mm Z-plug), S (Gold or Silver OCC spade) or E (Expanding plug versions as your requirements change. Expanding 4mm plugs are the standard configuration, please specify at time of purchase if you require an alternative connector. Alternative connector kits are available from your Atlas dealer.
