Chord PowerARAY Noise Reduction UK Mains Plug
The PowerARAY noise reduction plug is the latest addition to Chord Company's range of noise reduction and absorption devices. The PowerARAY is a next-generation high-frequency-noise-reduction device that works similar to the bestselling GroundARAY products and can be connected to unused mains power sockets (wall or distribution block) adjacent to those used to power your Hi-Fi equipment. The PowerARAY provides a low-impedance escape route for HF noise, reducing the amount entering a hi-fi system, lowering the noise floor and leaving more space for the music.
What The Chord Company say
Very high-frequency noise is all around us. Unfortunately, this noise can harm the performance of audio and video equipment.
The mains feed into most domestic listening rooms is at the end of a very long line of power delivery cables. Not only that, once the power arrives at your home it is then routed to your audio system/s and all the other domestic electrical goods, providing another opportunity for your mains to pick up unwanted HF noise. These power delivery cables are unshielded and highly susceptible to picking up noise on the earth, live and neutral. The idea behind the PowerARAY is to reduce high-frequency noise as much as possible and provide a consistent and worthwhile improvement to the mains supply just before entering your hi-fi system. The best place to locate a PowerARAY is in a spare wall socket or a distribution block, adjacent to the power cabling of your audio system.
This noise reduction plug operates in parallel to the power, so no current flows through it. This parallel filtering is applied to the live, neutral and earth and has been optimised to reduce as much high-frequency noise as possible. Chord do not use series filtering as this may affect the impedance and power delivery to your system.
PowerARAY development background
For years, Chord Company has been developing proprietary technologies to reduce both low- and especially high-frequency noise, many of which, such as shielding, can be found in its cable ranges today.
In 2012, Chord Company introduced a solution to reduce damaging HF noise present in the equipment itself: the company’s proprietary TunedARAY mechanical tuning system. Successive and more advanced variations, such as SuperARAY followed, but the ARAY designs were always specific to the cable they were working with, limiting the technology due to space and other design factors.
In 2017, Chord Company started to prototype a next-generation ARAY system, the GroundARAY, one that would work over the widest range of high frequencies possible, with very high efficiency. This ARAY was designed from the ground up, without any of the limitations imposed with cable design.
In 2023, Chord Company have released a new range of products, the PowerARAYs, that have been developed further from the on the ongoing research into the reduction of HF noise.
Installation
It's easy, simply connect the PowerARAY, have a listen to a piece of music and judge for yourself.
Safety advice
PowerARAY technology is unfortunately slightly microphonic so to combat this we have filled the entire cavity of the enclosure with a hard-set resin. In case of any malfunction, please do not try to open the PowerARAY as this may damage the unit, invalidate your warranty and possibly compromise your safety.

About Chord Company
English cable maker that designs and hand builds in Wiltshire, known for its ARAY conductor technology.
Chord describes its cables as designed and hand built in England, at Amesbury in Wiltshire. The catalogue covers interconnects, speaker cables, power cables, HDMI cables, Burndy cables and accessories. ARAY conductor technology, and its Tuned ARAY refinement, appears across several of the ranges, from analogue interconnects to digital and USB cables.

ARAY conductors appear in several ranges
ARAY is Chord's conductor geometry. The Signature digital cables pair it with silver-plated oxygen-free copper conductors, PTFE insulation and silver-plated braid and foil screening. Tuned ARAY is a later development of the same idea and appears in the Epic, Signature, Sarum and Shawline ranges, while ClearwayX carries ARAY.
Power and grounding get the same attention
Chord extends its ARAY work beyond signal cables, with PowerARAY, GroundARAY, PowerHAUS mains products and the PhonoARAY grounding product. ChorAlloy is another named Chord technology. Grounding and mains products work on a different part of the chain from signal cables, so they are the place to look when noise is the problem in your system.
Named ranges from one English maker
The ranges are Leyline, C-series, Clearway, Shawline, Epic, Signature and Sarum T, with ChordMusic as a further line. Chord describes its cables as English design and hand construction, so choosing a range comes down to your budget and your system, not to changing approach.

I placed mine in the empty socket beside the 8 socket extension and this version of the product doesn’t need power. I had it in place for a week, playing various genres of music on compact discs along with the TV and 4K player for broadcasts and films, which are all connected to the pre-amp, with films either on the streaming services Disney +, Amazon Prime or Blu-ray and 4K discs.
I unplugged it, and firstly, I was immediately struck by how suddenly the sound of the TV changed as well as the compact disc playback had gone from a warmer sound with a wide sound stage with more pronounced details in the music. In fact, the musicality of the CD player had changed, the TV sound changed as well, and the overall sound that I had enjoyed for a week had become an uncomfortable metallic-sounding playback, which I didn’t know I was listening to before the inclusion of powerARAY in my vintage Olive Naim set-up.
To my ears, the powerARAY isn’t snake oil but a worthy inclusion for a system. It is expensive, is the only downside I can think of...
