CYRUS i9-XR Integrated Stereo Amplifier

CYRUS i9-XR Integrated Stereo Amplifier-FIG1

Product Information

The i9-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

Power Amplifier
The wideband power amplifier of the i9-XR responds from D.C. to beyond 100kHz ensuring ruler flat frequency response and keeping any undesirable phase shifts out of the audio band. With a generous, over-specified power supply the i9-XR power amplifier is very capable of reproducing the scale and drama of the musical performance.
All new analogue preamplifier
Derived from the new high-end Pre-XR preamplifier, the i9-XR analogue preamp features relay input selection and a new high performance gain stage. This short-path design makes the analogue preamplifier extremely transparent. With four analogue inputs and phono MM, the i9-XR will cover just about any system requirement for analogue connectivity.
XR digital performance
The DAC input stage of the i9-XR features a new 2nd generation version of our award-winning QXR DAC, but with an all-new high-speed analogue buffer stage. Seven digital filter alignment options are user adjustable to suit the taste of the listener. Input options include USB audio (to 384k sample rate) and DSD to DSD256, 2 x SPDIF digital and 2 x optical digital inputs.
PSU-XR port
The i9-XR includes a port for the new PSU-XR power supply. 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 i9-XR a pair of these are assigned to provide ultra-smooth power for the preamplifier, and a second pair to provide a huge dynamic boost for the power amplifier.
Low noise phono stage for vinyl
Inheriting many design features of the award winning Phono Signature, the phono stage in the i9-XR performs at a level way above its class. Featuring low background noise and high dynamic range, the phono stage is a perfect complement for a quality vinyl turntable source.
Fully configurable
A new menu system makes the i9-XR highly customisable yet easy to set up. With a tree-style navigation structure and both local and remote control navigation, menu settings are quick and simple to select.

CYRUS i9-XR Integrated Stereo Amplifier-FIG2

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.
