CDi-XR

The CDi XR was designed as a reference integrated CD player, building on the legacy of the CDi and incorporating many novel technologies developed in-house at Cyrus over recent years. Housed within our iconic half-width chassis, the CDi-XR sits above the existing CDi and CDt models, offering a substantive performance upgrade.

Transport / Servo

Several years ago, Cyrus invested heavily in developing our own in-house CD ‘Servo’ mechanism, our ‘Servo Evolution’. The design principle is to read as much information as possible from the disc itself first time, rather than having to rely on ‘re-reads’ or ‘error-correction’.

Whilst it is true that the data on a CD is stored in ‘1s and 0s’, the way it is read, picking up different frequencies of reflected light, has analogue elements to it. Therefore, precision engineering can improve performance. Off-the-shelf mechanisms produce significant ‘system noise’ when the stepper motors of the mechanism are required to be used during the error correction processes when the data was not picked up on the first pass. Our ‘Servo-Evolution’ system reduces these re-reads and corrections by around 20%, producing not only a cleaner data stream for the DAC, but significantly less noise induced in the analogue output stages.

Containing Noise

Upgraded components along with intelligently designed circuits using ‘counter-current’ methodologies to reduce noise pickup are in evidence throughout the design.

The fundamental principle is that power starts at the ‘quietest’ part of the circuit, before flowing towards the ‘noiser’ sections. Less noise is therefore ‘carried’ or induced into the power paths, limiting the transmission of noise inside the product. Whilst this sounds logical, the application in practice is incredibly complex, and needs to be considered at a system-wide level. Even the geometric alignment of individual components has been optimized to facilitate the cleanest possible flow of power and musical signal.

The DAC has been housed on its own shielded section of the PCB, again to help contain noise transfer

Second Gen QXR DAC

The DAC in the CDi-XR is our own second-generation QXR DAC platform with a key notable difference in its implementation.  As a DAC usually has to handle a multitude of possible resolutions and input paths, their design is always a slight compromise on the best possible configuration for any particular source. In the CDi-XR, however, we know exactly which resolution is going to be received (44.1kHz, 16bit) and the incoming signal path that data is going to travel.  As a consequence, we are able to calibrate our QXR DAC with incredible precision. We are able to optimize, not just the inbound data path and the data conversion itself, but also the filtering stages of the DAC to render the finest analogue output possible.

Internal power supply

The CDi-XR, like all products in the XR series, has had a complete overhaul of the power supplies to each circuit section. The power supplies are much stiffer and have enabled Cyrus engineers to get the remarkable SE engine to run even more quietly.

Reviews

“The CDi XR is a CD player that manages to extract every bit of detail from all CDs. Not only is it technically perfect but also manages to incorporate a kind of analogue sophistication into the playback.” (Review in German)

“New Cyrus XR series products come into the market with high expectations. Maintaining the usual compact design of the British manufacturer and at the same time moving into the high-end category of integrated amplifiers and CD players was a technical challenge. The ten years of development work has paid off – the result speaks for itself!” (Review in German)

“Cyrus CDi-XR as a compact disc player is characterised mainly by three words: coherence, precision and resolution. And the fourth one – musicality. This player provides a juicy and complete sound of high quality, thus giving tangible evidence of the fact that the compact disc has a great potential, which you just need to know how to reach for correctly. And the British Cyrus can do it like few others!” (Review in Polish)

The CDi XR is dynamically agile and tonally very finely balanced. It delivers a vivid, precise and wide soundstage. Its performance is filled as much with tension as it is with sophistication.

“The sound has a texture, not particularly strong, and there is no obvious warm sound orientation, just good enough. The hall sound is the same, enough is good enough to bring you a sense of openness, while listening to the huge venue without affecting other frequency range, nor pursuing gorgeous, beautiful, it sounds like that you are listening to the “reality”.”

“It is very exceptional for small system shows an ideal soundstage. The music instruments are neat and organized. Openness, directness and main images served up close personal are the great music presentation from CYRUS.”
