Cyrus PSX-R2 Power Supply Upgrade

Almost any Hi-Fi component can be upgraded to higher performance using our techniques and components. The two things go together – the know-how and the right component. Over the last 30 years, we have developed our knowledge of where the biggest problems lie and how to overcome them to unleash better performance from a given piece of equipment.


Our Cyrus upgrades have really increased in popularity lately, so it was only a matter of time before we were asked if we could improve one of there PSUs. The successor to the PSX-R, the PSX-R2 is based on designs that has been in the Cyrus family for over 30 years.





Designed as an easy plug 'n' play upgrade for a number of Cyrus source components, the PSX-R2's primary feature is its large 300VA transformer that's designed to deliver an extremely smooth and stable DC feed allowing any partnered component to achieve its full potential and we certainly know the benefits of a good power supply, so we were very keen to see what extras we could bring to the this power supply.




The PSX-R2 is a well thought out design which provides a great platform to upgrade! Our upgrades build on the strengths of the power supply. Everything you love about the sound remains – it just gets so much better.


30 significant component upgrades/changes are made across the power supply. Upgrades include replacing the four slit foil reservoir capacitors with the brilliant Supertech caps and increasing capacitance to 40,000 microfarad.

Russ's favoured audio grade Panasonic capacitors which give a smooth and detailed sound are also fitted where possible.




The unit is completely disassembled to gain access to key areas of upgrade. Post upgrade, the unit is then soak tested for 24 hours.


To clean up and give the power supply an upgrade we fit a new IEC socket and a Silencer™ mains filter is also fitted.








The PSR-R2 is fitted with an internal fuse so that was of course, upgraded to a SuperFuse™ !


A short link cable that's hard wired, runs from the PSX-R2 into the component it's powering. This is upgraded using a woven Kimber TCX™ cable and then finished with a silver plated Neutrik connector.





If you don't have exactly the same model as listed above, but a very similar unit (such as the older PSX-R), then it's highly likely that the same or similar upgrades will apply. But we can't guarantee that until we have the unit here for inspection. Get in touch and let us know what you have.


Equipment upgrades are proving hugely popular. During peak times there may be a wait of several weeks before we can carry out the upgrade. So before we get your equipment here, it must be booked in so we can ensure a speedy turnaround of the upgrade. Once you have placed your order, we will contact you to arrange a suitable week and getting the equipment here.

In Person
For those of you who are local enough or if you fancy a trip to the lakes, you can drop off your equipment personally and then collect it when it’s complete or we can ship it back to you.

By Courier
We can arrange a courier collection of your equipment for an additional cost. We currently use UPS.
To make things easier, we can offer several collection options.

1. We can arrange a specific day for the courier to call and collect your equipment. Someone will need to be available all day at the collection address as we’re unable to arrange a time slot for collections.

2. Dropping off at a UPS Access Point. UPS use a network of local shops to deliver and collect parcels from and to. We can either post you a collection label or email you the label (you will need to print the label at home/work). Securely box up your equipment, affix the collection label to the outside of the box and take it to your preferred Access Point where you will be issued a receipt. UPS Access Points can be found here (link opens in a new window), simply enter you postcode to find your nearest one.
