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 Ultra RCA 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 metallic 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 Ultra.
The Conductor and Dielectric
Building on the work that led to the original groundbreaking Mavros, the new Asimi Ultra symmetrical RCA 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 so 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.This 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 'Ultra' Connector Plug
Designed in-house at Atlas, the modular design of the new Ultra plug is a clear example of the continuous development program into materials and technology embedded into the Atlas ethos. This new plug employs a novel approach to the problems of mass reduction, residual conductivity (eddy currents) and dielectric discontinuities, all of which can affect the mechanical and electrical properties of a cable. The all new Atlas Ultra has a 57% reduction in mass over its predecessor, employs an internal non-conductive sleeve matched to the dielectric properties of the cable (Teflon) as well as maintaining the renowned Atlas plug attributes of solder free construction, self-cleaning insertion and material consistency, all of which are formed from OCC thus ensuring a consistent signal path. High quality, exclusive, solder free Atlas XLR connectors are also available as an alternative.
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 Ultra, 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, whilst 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!
