  • Class-leading RF grounding device

  • Sophisticated frequency-optimised RF filter technology

  • Custom designed PTFE circuit board with audio-grade components

  • High-performance, nickel binding posts

  • Developing the Grounding System

    A standout range from the past few years has to have been our grounding products and the RF Routers. Following the publication of Russ’s grounding guide in 2015 setting out his preferred way of grounding equipment casework, he has been modifying and perfecting his method to deliver increased performance. The latest SuperRouter and SuperRouter Signature ground components are the culmination of this work.

    "SuperRouter features high specification, audio-quality components and intelligent circuitry to take performance to a completely new level. "

    What is RF Grounding?

    The principle of Russ’s approach to signal grounding is to connect equipment casework to a ground point. This can be an external earth rod (the preferred route), or via the external terminal on one of our SuperSockets, UltraSockets or Signature Sockets. It’s important to remember that this is not supplementing your existing electrical ground but is specifically providing a path to ground for RFI, limiting its negative effects on audio signals.

    The way these connections are made is significant, but the most important element of Russ’s grounding is the use of the RF Router. The Router acts as an efficient RFI shunt, optimised for RF frequencies and means that the connections made are efficiently and effectively routing RF noise in a circuit to ground – hence the name ‘Router’.

    The SuperRouter RF Ground Component

    While the existing RF Routers offer effective grounding, Russ knew that their performance could be improved upon. This led to the development of the two new SuperRouter products which incorporate everything we have learned about grounding over the last 40+ years. Where the RF Routers use more modest components, SuperRouters feature higher specification audio-quality components and intelligent circuitry to take performance to a completely new level.

    "SuperRouters offer our best RF grounding yet and – from our listening tests – they deliver the most musical sound we’ve achieved"

    Integrating the SuperRouter

    SuperRouters are designed to be used in the same way as our existing RF Router MKII, acting as the connection between the nominated 'hub' on your equipment and your grounding point. If you already have an RF Router, the SuperRouter is a straight swap.

    Connect a grounding cable from your equipment to one of the outside binding posts on the SuperRouter; the central terminal on the SuperRouter is the one to be used for connecting to your grounding point. Ideally, this is a separate, external earth rod, but you can also use the ground terminal on the front of one of our wall sockets.

    The SuperRouter is not supplied with any cables: it is designed to be used with our Technical Ground Weave cable - you can choose cable lengths and terminations here.

    Why multiple binding posts?

    The SuperRouter is used in exactly the same way as our existing RF Routers, but the increased number of ground terminals makes it easier to accommodate larger, more complex systems. The additional terminals also allow the new EVO-S PowerKords to be integrated into the Grounding System by providing ample ground terminations for multiple mains cables.

"the sonic gains were striking, with the system sounding more dynamically expressive, tonally richer and with a soundstage offering much improved dimensional resolution"
