Atlas Element Metik 3.5mm to Achromatic RCA S/PDIF Digital Audio Cable
3.5mm digital connections have become increasingly common with the popularity of high-performance ‘dual purpose’ personal audio devices and DACs such as the Chord Mojo.
The Metik range of cold-weld jack plugs brings the solder-free continuous signal path principles of Atlas' Achromatic and Ultra RCA connectors to portable device interconnects. Machined with precision copper-alloy contacts, with XLPE dielectric, these cables are a superb choice for connecting mobile devices without compromising sound quality.
Conventional jack plugs typically suffer degraded signal integrity,principally by using low-grade components, soldered connections and/or screw fixings which distort the cable dielectric (insulation), which produces measurable changes in the cable’s impedance. RCA connectors are Atlas' low-mass Achromatic phono plugs.

- Atlas Metik Jack Plug
- Achromatic RCA Plugs
- Silver-plated OFC Conductors
- PEF Dielectric
- Co-ax
Metik Jack Plug
The Metik is a robust, air tight metal to metal solder-free contact jack plug. Available in 2.5, 3.5 & 6mm versions.
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 which behaves as one continuous entity, with minimal degradation of the signal compared to soldered connections.
Atlas also developed their own low mass/high bandwidth connectors to take this approach to its logical conclusion.
Achromatic Plugs
Atlas’s expert electro-mechanical knowledge has led to the innovation of the next generation of RCA plugs. Known as the ‘Atlas Achromatic RCA plug’, Atlas has focused on improving both performance and appearance to create a higher performance starting point for their RCA 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 RCA plug. Firstly, the barrel of the Achromatic plug features a high stability ABS material. This is strong, stable and of superlative surface quality.
There is also an improvement to the Achromatic plug’s contact geometry, aiding the contact properties of the plug and the self-cleaning wiping action to ensure contacts are in optimal condition and to maximise signal transmission.
The third change Atlas made was around the rifling of the RCA pin. This improvement self-aligns the conductors during the cold weld processing, ensuring a superior stable connection.
Finally, there is a reduction in the overall mass of the RCA plug by 8% which has shown to improve signal transmission.
The above changes mean a solder-free, low mass, self-cleaning, recyclable RCA plug with a non-conductive body.
Silver Plated 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.

PEF 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). PEF (Foamed Polyethylene). The foaming process uses a blowing agent, of which there are two types. Atlas use the gas-foamed method which creates a more inert, consistent and higher quality product. 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.
