Bringing Clarity to your system

The Clarity-4 is a power conditioner utilising a type of technology called Coherence Technology. Clarity-4 works in a different way to our other power conditioners: we recommend using the Clarity-4 after you have fitted the Silencers and Purifiers.

The Clarity-4 units employ multiples of the ClarityMains modules wired in a very specific way and are designed to plug into your mains extension close to your system. Like our power conditioners, such as the Silencer, they are used in parallel; they simply plug into the mains and nothing plugs into them. Clarity-4 is mounted in a carbon fibre-effect box and is supplied with a YellO Power™ power cable. Plug it into a spare socket in the mains extension powering your Hi-Fi system, or use an unused wall socket close to your Hi-Fi system.

The versions

Clarity-4 is an enhanced version of our ClarityMains plug-in conditioner, using four of the ClarityMains modules for better performance and saving money, space and sockets. Our Clarity-8 combine eight of the modules for best performance.

About the Technology

The Clarity-4 is made for us by a technology company in the USA. To gain an understanding of what the device is and what it does, we spoke to the manufacturers to explain Coherence Technology. This is what they told us:

"Traditionally, there are three ways to improve an electronic circuit. You can improve the design, improve the materials and improve the ambient conditions in which the circuit operates. We believe that our Coherence Technology offers a fourth way of improving an electrical circuit.

"Coherence Technology neutralises noise inherent in circuits... noise that is caused by discrepancies of time and amplitude in the ground plane. By increasing the underlying coherence of the ground plane, the technology neutralises this noise. When we neutralise this inaudible noise there are improvements in the performance qualities of the audio signals. And there is also an improvement in the listener's ability to appreciate and gain greater entertainment value out of the sound reproduction."

Because The Clarity-4 is a passive filter, nothing needs to be connected to it for it to work. It simply needs to be plugged in with the socket switched on.

    Yes, I recommend this product.
    "Worth Every Penny"
    So please I bought this. As per advice on this site, kitted out with superclamp, mini purifier, zapperator and what have you first, then added this. 10 minutes in and vocals and instruments sound that little bit more nuanced. An hour or so and the difference is dramatic. It is as if a layer of banality has been stripped away. Every sound is more expressive, interest and enjoyment are up, significantly. An excellent buy.
