All Cyrus components are housed within our iconic half width die-cast aluminium chassis, which has now been in use for over 30 years across our entire range of Classic & XR products. Designed and built to last the test of time, every single chassis is hand finished using a process called linishing, resulting in every product we build being of the highest quality. As we all continue to be socially responsible, our use of the same chassis design has allowed us to upgrade
our customers’ products to the very latest components all within the original chassis, saving these old products from going to landfill and our customers making considerable savings too. We estimate that more than 80% of manufactured products remain in use today, making Cyrus one of the most effective users of materials in our industry by far.
Cyrus PSU-XR
Cyrus has nearly four decades of experience crafting award-winning products, designed and assembled entirely in-house at Cyrus in the UK. From the start, Cyrus’s mission has been to infuse the latest in technology with superb engineering to create ‘emotional’ musical experiences.
A fundamental step change in design approach for XR series has been possible due to an accumulated understanding of DAC technologies and power supply designs, combined with Cyrus’s recently updated manufacturing processes and the availability of higher-grade components. XR series, whilst faithful to the Cyrus core acoustic philosophy, provides remarkable sound quality benefits and substantially increased dynamic range, allowing every layer and nuance of the music to shine through. Indeed, the clarity and detail of the XR series will keep the listener wanting to go back and listen to tracks heard a thousand times before.
One of the driving principles behind the design of the XR series has been noise reduction whilst another significant area of focus was power supply design. Using only the best components, XR delivers outstandingly high quality and reliable power to every bit of the circuitry to ensure optimal performance.
The PSU-XR builds upon their extensive legacy in Power Supply design. Beginning with the original PSX, Cyrus has always led the field in producing clean, stable and ‘stiff’ external upgrade power supplies. ‘Stiffness’ is essential, Even when heavy loads are applied, the voltage has to remain completely stable. The PSU-XR employs the largest toroidal transformer we have ever used, coupled with some amazingly efficient load management circuits to deliver a staggering amount of power.
PSU-XR is able to deliver ‘exact’ power requirements to three different circuits on the host product, the PSU-XR significantly enhances the performance of any XR product it is used with. Advanced, microprocessor controls, relay switching, completely separated ‘Grounds’ to virtually eliminate the transfer of ‘noise’ and a future-proof architecture are just some of the special features of this upgrade power supply.
The PSU-XR communicates with the host-product via the 15pin bus lead to determine the exact voltage requirements of the various circuits to receive the additional power and then controls the output voltage using an 8-bit digital gate, allowing 256 different (and precise) voltage steps for the output rails.
The PSU-XR is able to supply three different circuits in the host product with power.
In order to preserve the purity of the power to each of these circuits, the different power sections of the PSU-XR have completely separate ‘grounds’. This virtually eliminates the possibility of system ‘noise’ from one section of the host product being transferred to another section.
Naturally, the XR series also features a new aesthetic. All products in the new XR series are wrapped in a new "Phantom Black" paint finish, introduced especially for the XR series. If you’re worried that they won’t coordinate with your existing Cyrus products, don’t fret. The colour is sympathetic to both the existing core and signature range.
