About the ATLAS Cables Arran Speaker Grun cables (pair)

Product Description

Come demo in store

We have the Arran RCA, Phono, Coax, XLR and speaker cable with Grun available to demo in store. We are an ATLAS approved retailer with the experience / knowledge and investment to assist you your speaker cable purchase.

The Arran Speaker Grun is an advanced wide-bandwidth OCC loudspeaker cable which represents the pinnacle of our design & manufacturing expertise.

A technically and sonically sophisticated loudspeaker cable created to fully complement the world’s finest audio components. Situated between our acclaimed Mavros and Asimi ranges, the Arran family 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 formed by air voids, cotton spiral and tension controlled wrapped PTFE is further enhanced by the SSG (super stabilised geometry) layer which maintains the cable symmetry constant over its length.

Termination is with our cold-weld Transpose Modular Termination System, and may be ordered with Z (Z-plug), S (spade) or E (Expanding) plug cold-weld connectors, the latter is the default factory-fitted option.

In a cold-weld (solder-free) connection, the metal of the connector plug and the wire are squeezed together under a 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.

Widely acclaimed by the world’s specialist audio press as a key element in achieving the highest possible level of system performance, results with our Arran cables are further enhanced by the configuration of our Grun cables and adapter options. (Basic adapter included).

Standard or Luxe finish options are available.

Grun Coherent Earthing System

The benefit of an independent system earth.
One of the biggest obstacles to achieving the performance levels our equipment is capable of is noise. Low levels of RFI (radio frequency) and EMI (electro-magnetic interference) and noise on the signal ground all subtly modulate and degrade the overall noise levels of the system.


Ironically, this is generally only noticeable when eliminated – even though much of this ‘noise’ is theoretically at frequencies beyond the range of our hearing. The main sources are noise in the mains supply and component ground connections – mobile phones, ‘wallwart’ chargers and wifi networks are major offenders – while a percentage is actually generated within the equipment itself. Generally things have got worse with the advent of computer audio.

The Grun Coherent Earthing System addresses these issues by providing an ‘independent’ earth for users of Mavros, Arran and Asimi Ultra interconnects.

*Speaker cables are part of low impedance circuits and as such are not as susceptible to electrical interference as analogue interconnects. However, speaker cables often radiate interference, consequently it is good practice to ground the screen if available to minimise any ‘antenna’ affects.


Grun interconnects are easily identified by the blue-green Ultra RCAs (interconnects) and ‘flying’ earth connectors.
