Atlas Achromatic Z-Plug.
Technology : Innovation in practiceClean, consistent cold-weld connections. We‘ve long championed the superiority of our cold-weld (crimped) connection over a soldered joint. Our precision-calibrated process results in an airtight metal-to-metal connection which avoids many of the typical issues in solder or screw fixing which can adversely impact the measured performance of the assembled cable.

A soldered connection creates an undesirable material ‘barrier’ in the signal path, as well as potential inconsistencies. Screw terminations can distort or damage the conductor and/or dielectric, resulting in measurable deviations from the intended specification.
To ensure the accuracy and consistency of our cold-weld connection process, we developed our own tools to apply the required pressure. The result is an uninterrupted signal path which effectively performs as one continuous entity. The process is employed on the connectors of all our analogue cables.
Factory-terminated Achromatic speaker cables feature our cold-weld precision crimp Z-plug, which is also an option for cables assembled to order by our international distributors and dealers, who are equipped with our proprietary tools and factory-trained in their use.

A screw connection version of the Achromatic Z-Plug, normally sold in packs of four, is available for DIY termination.



Attention to detail.
The construction and finishing of our Achromatic plugs is also vital to their performance.
Plug pins and contacts are necessarily gold or silver-plated* to prevent oxidisation, which affects performance, and visible tarnishing. The priority is to minimise contact resistance, which is critical to consistent performance.
* Silver is a more efficient conductor than gold, but is both more expensive and prone to tarnishing.The body of the Atlas Achromatic connectors is a low-mass, non-conductive (and recyclable) ABS design.
While ‘hifi jewellery’ metal plugs may be visually impressive, typically their mass almost certainly has an adverse effect on the delicate audio signal.
