Chord Company unveils Hi-Fi noise-reducing PowerARAYs

The Chord Company is promising to banish noise from audio systems with two new noise suppression devices, dubbed PowerARAY and PowerARAY Professional.

The plug-style PowerARAY connects to unused mains power sockets, both on walls and distribution blocks, adjacent to sockets used to power audio systems. It’s designed to provide a low-impedance ‘escape route’ for high-frequency (HF) noise, therefore reducing the amount of noise entering any adjacent system.

The goal is to provide a consistent, worthwhile improvement to the mains supply just before entering hi-fi systems. It’s available with UK, Euro (Shuko) or US connections.

PowerARAY Professional (pictured top) adopts the same application principles as PowerARAY, but promises to takes performance ‘to the next level’, via a separate, larger capacity case with damping isolation feet; this connects via a high-performance captive power cable from Chord Company’s premium Signature, Sarum or ChordMusic collections.

PowerARAY Professional utilises technologies developed for Chord Company’s proprietary SuperARAY and GroundARAY products, and operates in parallel with the electricity supply, so no current flows through it. This parallel filtering is applied to the live, neutral and earth, and has been optimised to reduce noise.

It’s not designed to sit between the electricity supply and Hi-Fi equipment. Chord Company says this allows for greater integration flexibility.

It targets HF noise by introducing a potential gradient that turns noise into heat. Inside, the internal earth, live and neutral parts benefit from connection to their own MainsARAYs, plus individual SuperARAYs.

All other internal parts are securely held in place by machined aluminium billet, with internal components enveloped by a special damping resin.

Both the PowerARAY and PowerARAY Professional can be used with other ARAY products, to compound hi-fi performance.

The PowerARAY retails for £550, while the PowerARAY Professional is priced at £5,500 (with SignatureX power cable); £6,000 (SarumT); £7,000 (ChordMusic)
