RUSS ANDREWS LAUNCH EVO-S POWERKORD WITH BUILT-IN GROUNDING

Russ Andrews Accessories is introducing its latest and says Russ, ‘ultimate’ PowerKord, the Russ Andrews EVO-S PowerKord, which incorporates a cable grounding system.

For many years, technical director Russ Andrews has been researching the effects of grounding on individual HIFI components.

The company espouses the use of a star grounding configuration, whereby the pre-amp or integrated amp is designated as the hub. The casework of each source component is then connected to the case of the hub and it, in turn, is connected to a Russ Andrews RF Router or SuperRouter, both of which direct the RFI to ground via a dedicated earth rod or via the mains earth.

The recently introduced SuperRouter has been designed to accept multiple grounding wires, which is where the EVO-S PowerKord comes in. This new cable is designed to enhance the RFI grounding of the equipment casework by grounding the mains cable itself, as opposed to earthing it, which is for electrical safety.

The Russ Andrews PowerKords are constructed using Kimber Kable woven geometry. The cable’s earth is helically wound around the braided 24 live and neutral conductors, which Russ Andrews claims helps to reduce noise induced in the earth. In creating the EVO-S as a grounded mains cable, the company investigated the use of external screens. This is something it has traditionally avoided as regular metal screens can act as an aerial attracting RFI, making the situation worse.

GROUND SCREEN

As Russ Andrews explains, “The solution was to create a floating Ground Screen, unconnected to the mains cable and made from 24 braided Kimber TCSS conductors of the same quality as the PowerKord. This Ground Screen is terminated inside a custom-designed interface on the cable, which is fitted with a 4mm banana socket and connected to the SuperRouter using a Russ Andrews Technical Ground Weave cable.”

Each component in the system can then be powered using an EVO-S PowerKord, in addition to the casework grounding, to provide a reduction in unwanted RFI.

The EVO-S PowerKord is available now. Owners of existing PowerKords can upgrade them to the new EVO-S under the standard Russ Andrews upgrade programme.
