Atlas Eos 4.0em UK Mains Power Cable

 

The Atlas Eos 4.0em UK Mains Power Cable is an ideal choice for audiophiles who are looking for a high-performance power cable to enhance their audio system. This cable features high-quality OFC conductors, a highly stabilised PVC dielectric and a hybrid carbon screen for superior protection against Rf radiation. The dual drain Rf termination ensures a firm and reliable connection, while the Intertek tested compliant cable guarantees safety and reliability. In addition, the cable's large conductor size (4.0mm2) ensures a maximum current capacity, resulting in an optimal delivery of power to your audio system. With its superior performance and maximum efficiency, the Atlas Eos 4.0em UK Mains Power Cable is an excellent choice for any audio enthusiast.

 

Here is what Atlas Cables say about the Eos 4.0em

It has long been known that the quality of mains power can have a dramatic effect on the high fidelity performance of audio systems. The delivery of quality power as well as the containment and robustness of the supply to conductor/air borne interference are now a critical part of most if not all product design strategies. Atlas set out to deliver a high performance, audiophile standard screened power lead that can improve the performance of the majority of HiFi systems.

The Eos 4.0em power cable utilises high purity OFC conductors, high efficiency stable PVC dielectrics as well as a new carbon loaded hybrid screening process. This allows the new Eos em cable series to deliver exceptional fidelity and superior protection against the threat of Rf radiation. The Eos em screen acts as a critical filter against harmful incoming Rf a.c. power contamination, it dumps these airborne and electromagnetic disturbance effects rapidly to earth via the Atlas dual drain system employed in the latest generation Atlas cables.

Minimising the effects of series resistance is critical for efficient power delivery. The Eos em series screened power cables confront this issue in two ways, the first being the availability of various sizes (cross sectional area) of conductor (1.5mm2 (Eos dd), 2.5mm2, (Eos 2.5em), 4.0mm2 (Eos 4.0em), The second being the reduction in contact resistance at the plug/socket interface which is accomplished by polished surfaces and deep silver plated contacts.

By comparison, a typical domestic power lead lacks the quality of component parts, screening layers, dual drain system and anti-vibration treatment that Atlas employs in Eos. Atlas Eos products are best used as part of a complete Eos Power Management System for maximum effectiveness.

 

Notable Features:

  • High current capacity OFC conductors
  • Highly stabilised PVC dielectrics
  • Hybrid carbon screen
  • Atlas dual drain Rf termination
  • Intertek tested compliant cable!

 

Atlas EOS Mains Plugs

Precision-machined mains connectors with silver-plated pins for low contact resistance. Available in UK (13A), Schuko & Nema versions depending on country of original supply. 

 

Atlas Eos plugs

 

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.

 

Atlas DD (Dual Drain) System

Normally screened cables suffer from screen distortion when they are prepared for production. (If you've ever wired a plug or connector which uses a screened cable, you've done this yourself, cutting back and probably twisting the screening braid for termination). This distortion of the screen has a measurable impact, effectively changing the impedance and therefore the performance of the cable.

Atlas' ‘dd’ configuration is based on a simplified version of the techniques they developed for their top-of-the-range Mavros and Asimi interconnects. Twin symmetrical drain wires (each attached to 180° segments of the plug) are inserted between a 100% copper/Mylar™ foil and screen. The unique dd system connects the screen effectively to the cable return/plug interface, meaning the cable can be terminated without distorting, twisting or mechanically stressing the precision-laid screen. The benefits are in maintaining a consistent low impedance load to the plug, and a total 360° screening against noise and signal loss caused by RFI (Radio Frequency Interference).

 

Dual Drain Rf Screening

A pair of identically matched conductors (one for signal path, the other acts as the return conductor) enclosed within a non-conducting screen and stabilised PVC outer wrap. The Eos em screen acts as a critical filter against harmful incoming Rf a.c. power contamination, it dumps these airborne and electromagnetic disturbance effects rapidly to earth via the Atlas dual drain system employed in the latest generation Atlas cables.

About Atlas Cables Made in United Kingdom

Atlas Cables are a major producer of interconnects and cables in the United Kingdom of Great Britain. All products are researched, developed and most are assembled in the Atlas purpose built factory in Scotland.

Many of these products are unique and use advanced techniques of production or manufacture in order to bring to the user the very finest quality products. With each new model we continue to push the boundaries of reliability and performance. It's little wonder then, that Atlas Cables have had so many mile-stone advances in the past and that Atlas Cables have secured so many awards in comparative tests against other products.

About Atlas Cables

Scottish cable maker that designs and builds its own conductors, connectors and cables rather than assembling bought-in parts.

Atlas researches, designs and produces its cables in Scotland, with a handful of exceptions. Many cable brands assemble off-the-shelf components, but Atlas specifies the conductors, insulation and terminations itself and tests the result in its own listening room. It offers a five-year guarantee on its cables.

The plugs are Atlas designs too

Atlas designs its own RCA plugs. The Achromatic and Ultra RCAs are built for low mass and high bandwidth, and the newer Metik connectors were developed for personal audio. Designing the connectors in house means Atlas is not limited to what an outside supplier already sells.

Three performance levels, with named ranges in each

The catalogue is arranged in three performance levels. Upgrade covers Element and Equator, Aspire covers Hyper and Ailsa, and High End covers Mavros, Arran, Eos and Zeno. You can choose the level that suits the rest of your system, then move up later without changing brand.

Custom options and a repair service

Atlas lists luxe and speaker termination options, so you can specify a cable to suit the equipment at each end. It also repairs, customises and upgrades its cables through a dedicated service, which means you can bring an older cable up to date instead of replacing it.

Why we stock Atlas

Atlas run pure copper conductors through most of the range rather than silver or silver plating. That gives a warmer, more forgiving balance than the silver-plated cables we sell. If your system is already leaning bright, Atlas is usually where we point you first. Hand-built in Scotland, and we have sold them since 2008.

Solid Performance 24 May 2025
Solid Performance.

No fancy stuff, purely performance.

Very Decent Cable 29 January 2025
I was looking for an upgrade for my system and replaced my old Merlin Black Widow power cable with Atlas. My first impression is that the built quality is much better. It is solid yet flexible; the weight can tell its quality. The connection between the plug and cable is great (vs. Merlin’s poorly assembled connection).

The sound quality has improved so much that you find the music comes out effortlessly (being pushed out vs. poured out naturally). But I have to admit that I used the QSA yellow fuse upgrade, so I can’t contribute the sound quality upgrade to either of them; I just combined both, and I have no regret.
