Atlas' most advanced copper speaker cable, available as a conventional stereo pair, 2–4 configuration or 4–4 version suitable for biwiring. Now featuring Atlas' Grun Coherent Earthing System! 

Atlas Mavros Grun 4-4 Speaker cable - Factory Terminated

 

Atlas's most advanced copper speaker cable, available as a conventional stereo pair, 2–4 configuration or 4–4 version suitable for bi-wiring. Now featuring Atlas' Grun Coherent Earthing System! 

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 encased in cotton, and an additional layer of paper, and then the assembly is wrapped in PVC and shrouded 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.’

Atlas's goal is to make cables with no discernable character or sound of their own, which would 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 Speaker Connector

The Transpose is a modular, cold-weld, air-tight, solder-free speaker plug. Interchangeable connector options are spade, Z-plug and expanding plug, available in gold or silver.

In a cold-weld 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 damage to the cable dielectric. The result is a smooth, uninterrupted signal path that behaves as one continuous entity, with minimal signal degradation compared to soldered connections.

Atlas Transpose Plugs Technical Diagram

Ohno Continuous Casting Copper (OCC Copper) 

The Ohno continuous casting method re-heats the extrusion as the molten copper is forced out of the mould 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, impurities will always produce a few boundaries. The frequency of boundaries created is quite insignificant. A typical crystal in a copper conductor drawn to 0.3 mm diam. using the OCC process is 125.00 metres 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 are delivered faithfully to the receiving equipment.

PTFE Dielectric
 

PVC (Poly Vinyl Chloride) is cheap to produce and, as such, is the most commonly used insulation in AV cables. However, PVC is the worst quality insulation a Hi-Fi or AV signal can encounter, as its high loss causes a significant reduction in signal velocity. PVC is better suited to power cables and should be avoided in Hi-Fi and AV signal cables.

Other dielectrics in common use are Polyethylene, Polypropylene and Polytetrafluoride Epoxy (better known as PTFE (Teflon™) or Teflon) and the new and unique Atlas (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.

The table below shows the properties of a selection of dielectrics. Though not used as a dielectric in Atlas' cables, PVC is included for comparison purposes.

Multi-Core + 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.

 

Grun Coherent Earthing System

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 (electromagnetic 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 our hearing range. 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.

 

Contact Enhancer Option

Future Shop recommends the DeoxIT Gold G-Series contact enhancer to ensure the best possible connection between your systems.

DeoxIT Gold is carefully applied to the plug contacts of your cable and is a unique conditioning solution designed to improve conductivity and provide long-lasting protection on gold, base metals and other precious metal contacts and connections. DeoxIT Gold penetrates plated surfaces, molecularly bonding to the base metals to seal and protect both surfaces.

The benefits of applying DeoxIT gold are:

  • Improved Conductivity
  • Maintained optimum signal quality
  • Reduced wear & abrasion
  • Prevents fretting/dendrite corrosion
  • Forms a protective anti-tarnishing coating
  • Stabilises connections between similar and dissimilar metals
  • Reduces arcing, RFI and intermittent connections

Please select this option from the above ‘Contact Enhancer’ drop-down menu, and our engineers will apply the contact solution to your cable connectors prior to shipping.

Termination

This cable is professionally terminated by Atlas Cables using Atlas's Modular Transpose Speaker plugs, available as gold-plated banana or spade, silver-plated banana or spade, or silver-plated expanding banana. Cables are professionally terminated using a cold-weld method by Atlas's engineers and guaranteed for 10 years. Cold-welding does not involve solder and means the plug is crimped around the conductors at 360 degrees' under very high pressure to form an air tight seal which prevents the conductors from oxidising. This forms a better contact than soldering. Furthermore, the conductor is in full contact with the plug, which is in 360-degree contact with the binding post of your equipment, which means the signal flow is maximised from the cable into your equipment.

Free Premium Cable Burn-In Service: Experience the Power of Nordost VIDAR 2 Machine

 

We are thrilled to unveil our upgraded cable burn-in service, now featuring the cutting-edge VIDAR 2 burn-in machine. At Future Shop, we strive to provide the best possible experience for our customers, and this enhanced service is designed to unlock the true potential of your high-end cables. Read on to discover the exceptional benefits and advancements offered by the VIDAR 2 machine.

Please note: We are unable to burn-in cables with stripped bare ends or BFA plugs. Cable burn-in occurs after your order has been processed for the selected time period. For custom-length cables, burn-in takes place after termination by the manufacturer or our skilled engineers.

 

 

 

The Nordost VIDAR cable burn-in machine seamlessly combines three vital functions into a single operation:

  • Neutralising charges around cables and insulation: The VIDAR 2 effectively dissipates any built-up charges, creating an optimal environment for signal transmission.
  • Deep conditioning into the conductor core: With its wide band and profound conditioning capabilities, the machine induces significant changes in signal passage through the metal, resulting in enhanced performance.
  • Ultrasonic surface conditioning of conductors: The VIDAR 2 employs ultrasonic technology to refine the conductor surface, further refining the signal quality.

In addition to all the advantages of its predecessor, the VIDAR 2 introduces remarkable improvements, including:

  • Complex burn-in signal with wider bandwidth and richer content
  • Enhanced directionality for cables
  • FOUR burn-in zones - including a new digital zone for USB, Ethernet, and Coaxial (BNC) cables.

Using a proprietary blend of composite and complex signals, the VIDAR 2 ensures comprehensive cable conditioning. The signal consists of ultra-low and ultra-high frequencies, surpassing video frequency ranges. The signal effectively penetrates the core at ultra-low frequencies by oscillating throughout the cable while swiftly traversing the surface at ultra-high frequencies. This transmission methodology counters harmonics and heterodynes between the two complex waveforms, improving signal performance throughout all cable layers.

Furthermore, the circuitry design boasts a unique feature that drives electrons above the conductor into the dielectric or insulation area. This process neutralizes any electrical charges that may impact the signal integrity. With the Nordost VIDAR, we go beyond merely sending ping-pong signals along the cable; we also ensure a balanced signal flow from the centre core to the outer shield in interconnect cables.

 

What does all this mean for you?

Conditioning your cables with the Nordost VIDAR yields remarkable benefits, including enhanced sound staging, heightened detail reproduction, and a more captivating and musical presentation.

We offer our cable burn-in service as a complimentary offering at the discretion of Future Shop. While we strive to accommodate all burn-in requests for the specified time periods, please understand that during exceptionally busy periods, we may be unable to fulfill all demands due to the limited connections available on the Nordost VIDAR cable conditioning machines.
