Atlas are regularly asked by users of single-brand systems from companies such as Naim and Linn if Atlas cables could improve their system without sacrificing its essential character. It’s relatively easy to deliver an improvement in a specific area, but more difficult to create a cable that improves on overall detail, accuracy and open-ness without losing the signature speed and character of these systems.

All Atlas cables are designed to impose as little of any inherent character as possible, achieved through careful selection of materials and construction methods, but they feel this latest generation Hyper cable is exceptionally transparent, allowing the equipment characteristics to be conveyed intact. The cable employs conductors comprising 72 0.25mm² high-purity OFC (Oxygen Free Copper) strands encapsulated within a carefully selected high-efficiency PTFE (Teflon) dielectric coating. The resultant conductor is embedded within an anti-vibration filler and finished in the Hyper gloss black sleeve.

Atlas Gold Plated Z Plugs

The Atlas Z plug has stood the test of time. Using beryllium copper for the contact area, It’s designed to make a 100% contact within the 4mm female socket. The body is made from copper and it’s available for home assembly with grub screws to make contact with the conductors. When factory fitted or fitted by an Atlas appointed custom cable centre, they’re cold welded under pressure in order to amalgamate the conductors to the plug in an air tight seal. The outer sleeve is finished in black coloured ABS or in a turned brass with a fine oven applied powder coat finish. The Atlas Z plug is justifiably considered to be one of best 4mm plugs available.

  • Low resistance
  • High conductivity
  • 80% copper with beryllium 4mm section giving 100% contact
  • Corrosion resistant
  • Accepts conductors up to 5mm diameter
  • Solder free for a cold weld air tight interface between the plug and conductor or grub screw contact for DIY enthusiasts

Achromatic Plugs

Atlas’s expert electro-mechanical knowledge has led to the innovation of the next generation of banana plugs known as the ‘Atlas Achromatic Z Plug’, Atlas has focused on improving performance to create a higher performance starting point for their speaker cables as well as eliminating variability in performance. This has been achieved by refocusing on materials and the assembly processes.

Atlas has made 4 key changes with the Achromatic Z plug. Firstly, the barrel of the Achromatic Z plug features a high stability ABS material. This is strong, stable and of superlative surface quality.

In addition, there is also an improvement to the plug’s contact resistance achieved by improving the compliance of the beryllium copper contact leaves featured on the Achromatic Z plug. Beryllium copper offers excellent conductivity of signals.

The third change was to upgrade the manufacturability of the plug for pneumatic tool processing.

Finally, there is a reduction in the overall mass of the Z-Plug by 35% which has shown to improve signal transmission.

The above changes mean a solder-free, low mass, self-cleaning, recyclable Z-plug with a non-conductive body.

Oxygen Free Copper (OFC)

OFC is produced through an extrusion process which takes place in an oxygen-free-inert-gas atmosphere. This leads to a reduced oxygen content (10 ppm) when compared to Tough Pitch Copper (TPC) and an improvement in conductivity which typically measures in at between 0.5% and 2% greater than TPC. The OFC process therefore produces a much higher quality audio cable than the TPC process. High purity conductors sound clearer than their unprocessed (TPC) counterparts because there are fewer crystal boundaries present to cause signal degradation.

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).

PTFE (Teflon™) is usually applied at higher temperatures and in combination with OFC conductors. OCC materials don’t like high temperatures (soldering, applying the dielectric etc) so application of a low temperature PTFE (Teflon™) or FEP work best with OCC conductors. This is especially critical at smaller conductor sizes.

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 Construction

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


This cable is custom-made according to customers specific requirements as selected by the various dropdown options above. Future Shop can terminate your speaker cable using either Atlas’ Gold Plated 4mm banana/BFA Z-Plugs or gold-plated spade Plugs. Cables are professionally terminated using a cold-weld method by Future Shop’s engineers and guaranteed for 10 years. The plugs are put on using a cold weld method with an official tool supplied by Atlas. 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, and the plug is in 360-degree contact with the binding post of your equipment which means signal flow is maximised from the cable into your equipment.

Cables with Achromatic Z Plugs are factory-terminated by Atlas engineers.
