Atlas Achromatic X RCA.
Technology : Innovation in practiceBuilding on the strong foundation of our Integra plugs, the Achromatic X RCA connectors feature calibrated, ultra-precise cold-weld (solderless) connection, a reduction in mass & contact resistance, superior conductivity – and most importantly, improved sound quality.

Ideally, cables shouldn’t add or subtract anything, but in reality, numerous factors combine to have an audible and measurable effect — which is a form of distortion.
One of the essential elements in the mix is the connector plug. Atlas recognised over a decade ago that the traditional CNC-machined metal-bodied RCA connector was a weakness, with demonstrably significant performance loss.
Our research showed that a Polycarbonate and latterly ABS for the plug body was a superior material, allowing us to create an RCA plug with a low dielectric constant, low-mass, non-conductive body but retaining the physical resilience and stability of a CNC-machined product.
The outcome was our original Integra connector, used in our entry-level Element and Equator cable ranges. Our policy of continuous product development leads us, in turn, to the Achromatic and Achromatic X RCA connectors, the latter featuring in the latest generation Hyper and Ailsa ranges.


When originally ontroduced our Achromatic connnectors established a new standard for their price point. So naturally we’ve improved them. Twice.
Low Mass, High Bandwidth Connectors.
With any cable, part of its function is to keep the outside world – primarily in the form of Radio Frequency Interference (RFI) at bay. The connector plug itself, and the connection, is part of that mechanism.
Our Achromatic X RCA connectors utilise low-mass non-magnetic connectors to minimise the negative effect of needless metal in the plug itself, which we view as compromising optimum performance.

The X Factor.
For the Achromatic X RCA, we‘ve refined the design still further in pursuit of creating a continuous signal path. The plug pins are now solid OFC (Oxygen Free Copper) rather than hollow copper-alloy. Additionally, we‘ve adopted a ‘rifled’ pin profile, enabling more consistent conductor alignment during the crimping process, and finally the PTFE part of the plug more closely matches the characteristics of the cable itself.
