Atlas Arran Transpose Grun Speaker Cables

DESCRIPTION AND FEATURES

IN THE BOX: 2 speaker cables – for 2 speakers

OCC speaker cable with Transpose Modular Termination

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 optimized by the SSG (super stabilized 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.

Transpose Modular Termination System

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.

Grun Coherent Earthing System

Zeno is supplied as standard with a 1m Grun cable and spade tag adapter for connection to the ground post on your amplifier.

The benefit of an independent system ground.

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 each subtly modulate and degrade the overall noise levels of the system.

Although our cables are all designed to minimize the invasion of external interference, it’s not possible to completely eliminate it.

But the audible benefits of substantially reducing it via our Grun products are considerable.

And the impact of Grun is cumulative. Adding additional Grun-enabled products reduces the impact of unwanted ‘noise’ still further.

Grounding critical components via the Grun system doesn’t alter the tonal balance or character of the system but audibly removes the effect of noise you probably didn’t realize was there.

The result typically reveals a greater level of fine detail, enhanced stereo soundstage and an improved ‘ease’ and naturalness.

Ohno Continuous Casting Copper (OCC Copper)

In 1985, Professor Ohno, from the Chiba Institute of Technology, developed his patented method for the extrusion of a grain-free copper wire. (Technical papers are available from the Japan Inst. Metals and from Chapman & Hall, publishers.)

When a pure metal solidifies, its crystals grow in a specific geometrical pattern (typical to that metal) emanating from a nucleus, rather like the dendritic growth pattern of a tree. The size of the metal crystals grown can be varied by repeatedly annealing metal such as is done in the LC-OFC process. The structure of a strand of copper may be likened to that of a bag of sugar. Every grain of sugar has a crystal boundary. In a conductor, these crystal boundaries (potential barriers) act as a non-linear resistance to the flow of electric current. It follows that, the fewer the boundaries, the less the effect there is on an electric signal as it propagates from one end of the conductor to the other. Atlas cables such as the Arran and Mavros use OCC copper, whereas the top of the range Asimi uses pure OCC silver.

The Ohno continuous casting method reheats the extrusion as the molten copper is forced out of the mold, and very slowly and gradually draws the grain or crystal down the conductor‘s length, creating a ‘single crystal structure.’ Actually, because no copper is 100% pure, there will always be a few boundaries produced by impurities. The frequency of boundaries created are quite insignificant. A typical crystal in a copper conductor drawn to 0.3 mm diameter, using the OCC process is 125.00 meters long!

The benefits are obvious, with almost no crystal boundaries, the audio signal is no longer impeded down the copper wire and more information and detail is delivered faithfully to the receiving equipment.

Microporous PTFE

Microporous PTFE (Teflon™) is a unique, low density dielectric material, phase stable at room temperature, which offers significant performance improvements over solid PTFE (Teflon™) dielectric designs.

Multi-Core and Solid Core Construction

A pair of identically matched conductors. One for signal path, the other acts as the return conductor, is enclosed within a non-conducting screen.
