The aim of the new Atlas Asimi project was to take a completely fresh look at cable design and to develop new techniques to create a cable that would satisfy the most demanding customers for years to come. We're now proud to reveal the extraordinary all new Atlas Asimi XLR interconnect.
The "best in class" brief looked at all areas of the design, from the materials used to create the cable and connectors through to the manufacturing processes. Specifically, we looked at whether an improved neutral high fidelity sound could be achieved using standard metal connectors, whether the capacitance cable load could be improved and whether the RF (Radio Frequency) rejection performance could be improved. Throughout the development process, we conducted iterative design and testing to achieve our aims, with the resultant cable being the all new Asimi XLR.
The Conductor and Dielectric
Building on the work that led to the original groundbreaking Mavros, the new Asimi XLR adopts the latest world-leading construction, but with the added benefits of pure silver conductors, manufactured using the highest-quality technique for drawing pure silver, "Ohno Continuous Cast" or OCC. Using OCC solid silver in the manufacture of high quality Atlas cables increases the conductivity of the material by ensuring that there is less than one grain or signal deleting crystal boundary in about 125m of conductor! OCC silver allows the signal to travel through a continuous conductor instead of traversing repeated grain boundaries - in other words, the signal has a faster, cleaner and more direct path to follow.
The best realisable dielectric is air and in an ideal world, suspending the conductor in free air would be the best method to transfer maximum fidelity. However, this is not practical, I know a dielectric is necessary to 'protect' the conductor. To achieve the necessary amount of protection without increasing inefficiency, Atlas has developed a new technique, which uses a microporous PTFE (Teflon) tape, which is wound around the OCC solid silver conductors, then covered again and stabilised using a protective FPE (Flexible PolyEthylene) dielectric. This process allows the required geometry of the conductor to be maintained and offers greater manufacturing consistency. This new air spaced tape improves on the performance of the best solid teflon or PTFE insulators, by providing a 30% greater signal velocity and better integrity, particularly in the area of high frequency delivery. This VOP (velocity of propagation) is achieved because the new material has a dielectric constant of around 1.3 - significantly better than the 2.1 achieved by the more typical PTFE insulators which up to now were the best available in HiFi or audiovisual applications.
The construction of the new Asimi silver interconnect cable consists of a pair of conductors, each made up from six bundles of 12 multi conductor wires plus a thicker wire in the centre, which in turn is covered by a continuous Copper-Mylar electrostatic screen and a silver plated copper close weave shielding braid ensuring the minimal pick up of RF interference and noise. The outer sheath is made from hard wearing PVC covered by a decorative light grey woven cotton.
The Asimi interconnect is supplied terminated with the Atlas OCC solder free XLR connectors.
RFI (Radio Frequency Interference) is a major factor in cable design, especially now with the amount of ambient electrical wireless signals present in the majority of homes. To combat RFI, traditionally a metallic barrier (or braid) is encased around the insulated conductors and terminated at one or both ends. The predominant industry wide methodology of terminating the braid to the plug involves the braid being partially removed and twisted, therefore reducing the integrity of the screen, introducing mechanical screen distortion and thereby delivering an inconsistent RF performance. For the new Asimi XLR, Atlas has developed a new system that uses two symmetrical drain wires (each attached to 180 degree segments of the plug) inserted between a 100% copper Mylar foil and SPC screen. This unique system connects the screen effectively to the cable return plug interface and provides total 360° screening; not distorting the integrity of the screen in any way.
The Asimi interconnect cable is designed to be 'invisible' and has been designed by Atlas to reveal the entire content of the recording. In listening tests, the results are surprising; the Asimi introduces an air and ambience of sound hitherto hidden. Visit an Atlas stockist, listen and prepare to be amazed!

Atlas Cables? Who are we?
We are a Company of Great Britain, independent and successful. We design and build products Atlas because we have spent our lives in Industry Hi-Fi audio and video, and we are still excited about our passion.
Apart from a couple of exceptions, all products in the Atlas are planned, designed and produced in East Ayrshire, Scotland.
Scotland has a long tradition of specialists in the design and construction, that have given life to Companies in the Hi-Fi world-famous: this allows us access to a workforce of excellence, with vast experience in the field.
Performance Recognized at International Level
The audio cables , Atlas Cables have received numerous awards and recognitions in more than 30 Nations in which they are distributed. Our products ‘state of the art’, as the award-winning models of cables Mavros and Asimi, are considered to be among the best products on the market, and have received numerous awards in Europe, USA, Canada, Japan and the near East.
This is what he published in the English magazine "HiFi Plus" when she awarded "Product of the Year 2009", our cable signal is "Asimi", pure silver:
It's hard not to be seriously impressed with Atlas’ Asimi and Mavros pairing. These are two of the very, very best. Plus it's good to find a truly UK high-end offering. Atlas is definitely on the high-end map!
If you have used in the past, our cables Hi Fi, you already have an idea of what you can expect. However, if you've never tried before, be prepared to be amazed.
