CYRUS CDi-XR CD Player
Product Information
The CDi-XR is one of the first wave of products, heralding the new XR series
of Cyrus components. The familiar Cyrus precision die-cast case is the same,
but everything else has changed. With ground-up engineering inside, an all-new
phantom black paint finish, touch sensitive controls and a higher resolution
display that is customisable for brightness, contrast and polarity, the high
quality finish of XR makes a strong statement.
There’s no shortage of innovations and upgrades under the skin. XR series
products are the manifestation of over a decade’s accumulated technology and
development knowledge. With particular attention to the detail of every
component that lays in the audio path, XR takes Cyrus audio performance to
another level.
Features and benefits
Servo Evolution
The Cyrus philosophy for reading CD has always been the same – read it once
and read it accurately. The latest iteration of Cyrus SE technology in the
CDi-XR does exactly this, streaming the data from the disc to the audio
processing circuitry with precision and accuracy.
DAC Technology
The CDi-XR DAC design includes the highest specified Sabre DAC. This,
partnered with a high-speed analogue stage with excellent dynamic range
delivers exceptional noise and THD performance from the DAC stage.
Power supply design
Within a CD player is a complex mix of signals including fast digital audio,
sensitive analogue audio, high current servo and system control. To minimise
interaction between these circuit stages the power supply design of the CDi-XR
is completely segmented. The digital control circuits run from a dedicated,
high-efficiency supply, with other parts of the player powered from an over-
specified linear power supply with toroidal transformer. Nine individual stage
regulators smooth and distribute power within the player
according to demand.
PSU-XR port
The CDi-XR includes a port for the new PSU-XR power supply upgrade. Thirty
years ago Cyrus broke new ground with the introduction of the PSX-R, the first
ever regulated power supply upgrade that automatically adapted to match
perfectly the power requirements of any connected product. The PSU-XR raises
the bar by sourcing no less than five independent regulated supplies in a
single box. For the CDi-XR four of the PSU-XR power supplies are employed. One
pair to provide ultra-smooth power for the analogue audio circuitry, one for
the current-hungry demands of the motors and one just to provide an ultra-
stable supply for the PLL digital master clock circuit, reducing any power
supply related jitter to a minimum.
Configurable options menu
A new menu system makes the CDi-XR customisable yet easy to set up. The tree-
style navigation structure has display, time-out, and system configuration
options. Menu settings are quick and simple
to select.
CDi-XR CD Player
All Cyrus components are manufactured in an advanced die-cast aluminium chassis and this hand-finished casework is an integral part of the products’ sound. It’s not just about good looks; the chassis composition is specifically designed to create an electronically shielded and mechanically vibration-free environment for the sensitive audio circuits which are hung inside the inverted chassis, avoiding unwanted electric currents and secondary magnetic fields so the sound you hear is the very best that it can be.
