Mavros GRUN ULTRA

RCA interconnect cable based on the same design objectives and manufacturing techniques 

developed for our Asimi range, utilising copper rather than silver conductors.

 

The new generation Asimi now features our Grun Coherent Earthing System.

The Mavros Ultra RCA is a high speed wide-bandwidth interconnect designed to complement 

he performance of ‘high-end’ audio systems by achieving maximum signal transfer.

The Mavros Ultra RCA uses the very highest quality ‘6N’ (99.99997% purity) copper manufactured 

using the OCC ‘Ohno Continuous Cast’ technique. Cables manufactured with lower grade materials and 

 

poor manufacture typically have a coarse, grainy structure which compromises sound quality. 

In the manufacture of Mavros, we maximise the copper’s conductivity by ensuring that there is 

typically one grain in approximately 125 metres of conductor, allowing the signal a 

continuous unbroken path –in practice, 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 with copper shielding braid, ensuring minimal susceptibility to 

RF interference and noise.

 

Theoretically, the best dielectric (insulation layer) is air. Conventional dielectric (insulation) 

materials impose their own signature distortion and loss on the signal. Our 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 our low mass, high bandwidth, cold-weld Ultra RCA or XLR connectors, 

both of which have minimal effect on the integrity of the signal.
