PRODUCT FEATURES

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.

Analogue Preamplifier
Derived from the 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.

PSU-XR Port
The i9-XR includes a port for the PSU-XR external power supply, which 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
Inheriting many design features from 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.

Digital Performance

The DAC input stage of the i9-XR features the 2nd generation of our award- winning QXR DAC, but with a highspeed 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
