Atlas Arran Transpose Bi-wire Speaker Grun Is a High-End OCC Copper Speaker Cable for Audiophiles Demanding Ultimate Performance
Atlas Arran Transpose Bi-wire Speaker Grun is a wide-bandwidth OCC copper speaker cable engineered for high-end audio systems requiring exceptional clarity, detail, and flexibility. Built using the Ohno Continuous Casting process, the Arran Speaker Grun cable delivers extraordinary signal integrity through six solid ‘6N’ purity OCC copper conductors and features modular termination for seamless system upgrades or configuration changes.
Atlas Arran Transpose Cable Delivers Sonic Transparency Through Ultra-Pure OCC Copper
Atlas Arran Transpose Bi-wire Speaker Grun is designed to extract every nuance from a high-resolution audio signal by utilising ultra-high-purity 6N OCC (99.99997%) elongated crystal copper. The cable’s six solid core conductors are manufactured using Ohno Continuous Casting, a technique proven to minimise crystalline boundaries and signal distortion. This uninterrupted grain structure allows for significantly reduced resistance and unmatched conductivity, ensuring optimal signal transmission and tonal fidelity in complex stereo or multi-amp configurations.
Atlas Transpose Modular Termination System Enables Future-Proof Connectivity
Atlas equips the Arran Transpose Speaker Grun with its proprietary Transpose Modular Termination System, offering flexibility for evolving audio setups. This system allows users to easily switch between Z-plugs (gold or silver), spades (gold or silver OCC), or expanding 4mm plugs without replacing the cable. Every termination is cold-welded, creating a precision-calibrated, solder-free metal-to-metal interface that avoids dielectric deformation and guarantees a seamless electrical path. This results in enhanced contact integrity, mechanical stability, and sonic purity, especially across bi-wire and bi-amp speaker configurations.
Bi-wire Configuration Enhances Channel Separation and Reduces Crossover Distortion
Atlas Arran Transpose Bi-wire Speaker Grun is offered in 2–4 and 4–4 configurations, making it ideal for high-fidelity loudspeakers with separate crossover paths. By electrically isolating the high and low frequency sections of the crossover, bi-wiring allows each amplifier channel to drive only part of the speaker’s range, reducing interaction and enhancing soundstage clarity. When combined with the low inductance (0.915 µH/m) and extremely low resistance (0.00384 Ohms/m) of the cable, the result is greater dynamic control, deeper bass, and cleaner treble articulation.
Super Stabilised Geometry Maintains Signal Consistency Across the Entire Cable Length
Atlas integrates its proprietary SSG (Super Stabilised Geometry) technology within the Arran Speaker Grun to maintain consistent conductor alignment and spatial geometry. A tension-controlled PTFE wrap, cotton spiral filler, and air-void dielectric structure work in harmony to ensure symmetrical signal transmission across the entire 17.5mm cable diameter. This uniformity reduces microphonic effects and electromagnetic distortion, supporting precise image placement and tonal balance, even at high playback volumes or in long cable runs.
Grun Coherent Ground System Minimises Noise for Cleaner Audio Reproduction
Atlas Arran Transpose Bi-wire Speaker Grun incorporates the Grun Coherent Ground System as standard, enabling the cable to reject low-level interference that often contaminates system grounding. This system allows connection via Grun leads and spade adapters, included in the premium package. When combined with optional Grun mains adapters, the result is a fully coherent star-grounding topology that dramatically reduces hum, hash, and background noise, revealing microdetail and enhancing spatial realism across the soundstage.
Luxe Aesthetics and Thoughtful Accessories Reflect High-End Attention to Detail
Each Atlas Arran Transpose Bi-wire Speaker Grun cable arrives in premium blue box packaging, accompanied by white cotton gloves, a cleaning cloth, a USB stick with documentation, and a set of Grun spade adapters. The cable's outer blue fabric jacket not only provides a tactile, durable finish but also complements luxury system aesthetics. Luxe finish options are available, allowing visual customisation to suit high-end home audio environments without compromising technical performance.
High-End Specifications Ensure Compatibility and Durability in Demanding Systems
Engineered with a solid core OCC copper construction and dual-layer foil/braid screening with dual drain wires, the Arran Speaker Grun offers superior shielding against electromagnetic interference. Capacitance is tightly controlled at 103.3 pF/m, ensuring consistent signal integrity in both short and extended installations. The robust 17.5mm outer diameter houses advanced dielectric layers made of microporous PTFE and precision-formed air voids, optimised to maintain dielectric linearity and suppress signal degradation over time.
Atlas Arran Transpose Bi-wire Speaker Grun Supports Long-Term System Evolution with Upgradeable Connectors
Fitted as standard with expanding 4mm plugs, Atlas Arran Transpose Bi-wire Speaker Grun accommodates future system changes through its interchangeable Transpose termination modules. Whether upgrading amplifiers, changing speakers, or reconfiguring for bi-amping, users can quickly switch connector types using authorised kits available through Atlas dealers. This upgradeability makes the cable a long-term solution for discerning audiophiles seeking stability, flexibility, and enduring high-end performance.
