Atlas Mavros 2-4 Grun Bi-wire Speaker Cable (Stereo Pair)
Our most advanced copper speaker cable, available as a conventional stereo pair, 2–4 configuration or 4–4 version suitable for bi-wiring.
A superior speaker cable suitable for ‘high-end’ audio systems.
Mavros uses very high purity OCC (Ohno Continuous Casting) copper conductors. The OCC process is named after professor Atsumi Ohno, who in the late 1970s, discovered that by heating the drawing mould to a higher temperature than the molten copper you intend to cast, then cooling it soon after, the result is one long, high purity (99.9997%) metal crystal.
These high-purity monocrystal conductors are used in a multi-stranded layout, wrapped in individual low-loss microporous PTFE (Teflon™) insulators, and twisted to help lower electromagnetic interference. The four separate conductors are then wrapped in cotton, an additional layer paper, then wraps the assembly in PVC and shrouds it in an outer black cotton sleeve.
In the bi-wire 2–2 and 2–4 configurations, two additional solid conductors are dedicated to the mid/high frequencies, facilitating a more stable and open stereo image.
This obsessive attention to detail – and the combination of materials & assembly methods which was only finalised after exhaustive testing – produces a cable which HiFi World’s reviewer described as‘ the best he’d ever heard’ and HiFi Plus summarised as ‘one of the very, very best. ’
Our goal to make cables which have no discernable character or sound of their own, which would in itself be a form of distortion – Mavros is engineered to ‘disappear’ in your system, leaving the performance of your equipment to speak for itself. It should be noted though that Mavros requires a ‘burn-in’ period during which the sound will continue to improve.
Transpose Modular Termination System
This cable is fitted as standard with the Transpose Modular Termination System, which allows easy switching between expanding 4mm connectors, spade and Z-plugs 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.
Grun. Coherent Earthing System.
An independent system earth engineered to reduce the RFI and EMI ‘noise’ which frequently degrades audio performance.
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 and Asimi Ultra interconnects and Mavros speaker cables* with the new Grun configuration.
