Atlas Mavros Ultra Grun Stereo RCA Interconnects

Mavros Ultra RCA is a premium high-end RCA interconnect cable based on the same design objectives and manufacturing techniques developed for the Atlas Cables top-line Asimi range, utilising copper rather than silver conductors.

Mavros Ultra has been designed from the ground up to complement the performance of high-end audio systems by achieving maximum signal transfer with minimum susceptibility to spurious interference.

Mavros Ultra RCA use the very highest quality 6N (99.99997% purity) copper manufactured using the OCC (Ohno Continuous Cast) technique. Interconnects manufactured with lower grade materials and poor manufacture typically have a coarse, grainy structure which compromises sound quality.

In the manufacture of Mavros, Altas maximised the conductivity of the copper by ensuring that there is typically one grain in approximately 125 metres of conductor. This allows the signal a continuous unbroken path, which in practice means the signal has a faster, cleaner and more direct path to follow.

Mavros Ultra 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 with copper shielding braid, ensuring minimal susceptibility to RF interference and noise.

Theoretically, the best dielectric (insulation layer) is air. Conventional dielectric materials impose their own signature distortion and loss on the signal. The Atlas technique uses a microporous PTFE (Teflon™) tape, which is wound around the core conductors, then covered again and stabilised using a protective FPE (Flexible PolyEthylene) dielectric. This process maintains the required conductor geometry, and bestows greater manufacturing consistency. Termination is with the low mass, high bandwidth, cold-weld Ultra RCA connectors, which have minimal effect on the integrity of the signal.

Technology

• Ultra RCA Connector - Ultra is a wide-band, OCC copper, constant impedance, self-cleaning, solder-free construction RCA plug.
• OCC Copper 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...
