The Cyrus 40 PSU is the intelligent PSU upgrade that works with every component within the 40 series.


Power

Cyrus has a long-standing tradition of designing external power supplies, dating back to the launch of the PSX in the 1980s. The Cyrus 40 PSU proudly upholds this legacy, embodying cutting-edge technology in an elegant, compact chassis. Equipped with its own on-board microprocessor, the 40 PSU seamlessly connects to all 40 series products, intelligently adjusting power configurations to deliver optimal performance across a full spectrum of voltage outputs.

A New Beginning

Housed in a sleek, brushed aluminium case, the 40 PSU exudes sophistication while delivering remarkable functionality. The 40 PSU features multiple digitally controlled power supplies, ensuring exceptional stability and near-silent operation. Its versatility is further enhanced by its compatibility with both the 40 series and PSU-XR models, providing added flexibility for current Cyrus product owners.

The 40 PSU contains five independent power supplies, routed through a multi-way umbilical cable to a connected 40 series component. These include a high-capacity logic supply for digital circuitry, two fixed voltage supplies for sensitive analogue components, and two variable high-capacity supplies for analogue circuits. The variable supplies also feature unregulated voltage settings for powering high-consumption circuits, such as power amplifiers, ensuring exceptional performance across all devices.

Features

  • Two fixed voltage power supplies intended to power sensitive, low-voltage analogue circuitry.
  • Two variable voltage high-capacity power supplies designed to supply power to low or high consumption analogue circuitry.
  • The variable power supplies also feature two unregulated voltage settings that can be applied to enhance the power supply for high consumption circuitry, such as power amplifiers.

Testimonials

Bought some Rega Kyte speakers, stands and chords from DB online and they were incredibly helpful. They updated my delivery address very quickly and recommended a longer cut of cables which they did complimentary. They also noticed I didn’t order with banana plugs so called me back to double check, which I did mean to order. When i had some issues connecting my cables and speakers, I called for some advice which they happily gave. Excellent service and next day delivery to London. Thoroughly recommend.

Probably one of the best companies in the world. They had to special order in the speakers which took a fair bit of time, which is totally understandable, but they kept in touch with me throughout the entire time with updates (even on a Sunday!!!) and once the speakers were with them, they were dispatched and arrived next day.

The entire sound system that I purchased is insanely good, but still not as good as Doug Brady HiFi!

I have recently purchased a HiFi package with Doug Brady and I could not be more thrilled with my experience with them.
When I walked into the store, I was made to feel welcome and was introduced to some of the products. I produces a list of specific items I was interested in and John was really helpful in showing me these items. He set the system up so I could experience it, he made some suggestions which made the package even better. Nothing seemed too much trouble for him, he was very knowledgeable about the products and gave great advice. I didn't feel pressured to buy anything, or didn't feel that he was upselling at any point. I left with an amazing package and I'd like to thank John and the team for the fantastic experience.

It’s now two weeks since I bought home my new system and I wanted to say thanks again for all your help, advice and guidance, not to mention cups of tea. I now have a system that meets all my requirements and sounds fantastic. Special thanks to Jon, who I hope is on the road to recovery from his operation and to Roger, who helped me finalise my choice. The Rega Saturn, Hegel H190V and Dali Rubicon 2 is undoubtedly the best system I have ever owned.
