Atlas Asimi Ultra Grun Luxe Stereo RCA Interconnects

Asimi Ultra RCA is a state-of-the-art pure silver interconnect designed to be effectively invisible in the replay chain and to reveal the entire content and ambience of the recording without any sense of exaggerated detail or brightness.

The Asimi is the only interconnect cable included in HiFi News magazine’s 2017 annual collection of best-reviewed equipment. They described it as "a true flagship cable."

The original aim of the Atlas Asimi project was to take a completely fresh look at cable design and, where necessary, to develop new techniques to create a cable which would satisfy the most critical listeners for years to come. For this latest generation version, they again went back to basics, re-assessing their existing design & manufacturing processes, exploring different construction methods and experimenting with new materials.

Asimi Ultra features pure silver conductors, manufactured using the highest-quality "Ohno Continuous Cast" technique for drawing pure silver. Silver cables have a reputation for poor sound quality in some quarters, however Atlas believe the Asimi definitively shows the problem is with low-grade materials and poor manufacture, resulting in a cable with a coarse grainy structure which compromises sound quality. By contrast, Asimi maximises the silver’s conductivity by ensuring that there is typically one grain in approximately 125 metres of conductor, allowing the signal a continuous unbroken path. In effect, the signal has a faster, cleaner and more direct path to follow.

The cable consists of a pair of conductors, each made up from six bundles of 12 multi-conductor wires, plus a thicker centre wire. This in turn is covered by a continuous copper/Mylar™ electrostatic screen and a silver-plated copper shielding braid, ensuring minimal susceptibility to RF interference and noise.

Theoretically, the best dielectric (insulation layer) is air. Suspending the conductor in free air would be the best method to transfer maximum fidelity, if not very practical. Realistically a dielectric is necessary to protect the conductor, although all conventional dielectric materials impose their own signature distortion and loss on the signal.

Atlas developed a new technique, using a microporous PTFE (Teflon™) tape wound around the core conductors, then covered again and stabilised using a protective FPE (Flexible PolyEthylene) dielectric. This process allows the required conductor geometry to be maintained and offers greater manufacturing consistency. Termination is with low mass, high bandwidth Ultra RCA connectors, which have minimal effect on the integrity of the signal.

The result is the best that Atlas Cables currently know how to make. Asimi, perhaps more than any other product, is responsible for the company being viewed as one of a handful of top manufacturers worldwide.

Atlas Cables offer a range of special Luxe finish options for this top-of-the-line audiophile cable. Four standard leather colours plus optional finishes available in contrasting or self-colour stitching options. Bespoke colour matching options (RAL or Pantone) are also available.

Please contact Audio Sanctuary to discuss your requirements if you would like to pursue the Luxe options.

Technology

• Ultra RCA Connector - Ultra is a wide-band, OCC copper, constant impedance, self-cleaning, solder-free construction RCA plug.
• OCC Pure Silver Conductor - The Ohno Continuous Casting process was developed by Professor Ohno, from the Chiba Institute of Technology, to manufacture a very high purity single grain copper or silver. There are only a handful of companies in the world manufacturing via this method.
• PTFE Dielectric - Microporous PTFE (Teflon™) is a unique, low density dielectric material, phase stable at room temperature, which offers significant performance improvements over solid PTFE dielectric designs.
• Twin Multi-Core Construction - A pair of identically matched conductors (one for signal path, the other acts as the return conductor) enclosed within a non-conducting screen. Combined with the Atlas Cables dd (dual drain) system which avoids distortion of the screening braid during assembly, which can change the impedance and therefore the performance of the cable.
• Grun Coherent Earthing System - An independent system earth which eliminates low-level RFI, EMI and noise on the signal ground. Read more...
