Cyrus Audio announce a revolutionary new approach to Power Supply Design.

Cyrus PSU-XR

Cyrus Audio announces the most intelligent power supply it has ever designed – the long-awaited PSU-XR. The PSU-XR power supply provides a sound upgrade for all Cyrus XR components. The PSU-XR is the first power supply from Cyrus to have its own built-in microprocessor. This enables it to talk to the product it is connected to, providing the best configuration of power sources demanded by the host product.

Flexibility is at the heart of the PSU-XR design. It can work with all of the products from the current XR range. It has also been developed to be future-proof, with all XR products still to be launched — including the Blu-OS XR streamer — which will require only a simple software update to enable it to talk to the PSU-XR.

As with every product in the XR series, noise has been reduced wherever possible, and the PSU-XR is no different. Output voltages from the PSU-XR are all digitally controlled, so therefore are extremely stable and virtually noise free.

Ceri Williamson, Head of R&D at Cyrus Audio says, “The PSU-XR is our best performing power supply, capable of providing up to 60% more power than the award winning PSX-R2 and due to its revolutionary design, is up to 50% more efficient.”

“The sonic improvements made when connecting the PSU-XR to a host XR product have been outstanding in our opinion”, says Chris Hutcheson, Head of Marketing, “however, as with every Cyrus Audio product, we encourage you to take some of your favourite music to your local retailer and let your ears convince you!” ​

The Cyrus Audio PSU-XR — alongside the rest of the XR line-up — will be demonstrated at this year’s Bristol Hi-Fi show from Friday 24th – Sunday 26th February 2023.
