i9-XR Integrated Amplifier

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.

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.

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

Power Amplifier

The wideband power amplifier of the i9-XR responds from DC 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.

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.

Roon Approved

The i9-XR is approved Roon Tested (using min firmware v1.6)

Being Roon Tested means that Cyrus and Roon have collaborated to ensure you have the best experience using Roon software and Cyrus equipment together, so you can just enjoy the music.

“Extremely agile, fluid and dynamic Integrated amplifier with powerful DAC. The XR series scores highly thanks to fine detail and a new, even higher quality level. A highly musical experience!” Stereo – December 2020

“With the i9-XR I think the company is on to a good thing. This amplifier offers excellent sound quality at the price, but in a lovely, small and neat package with excellent build quality. Sonically it delivers impressive clarity, and dynamics and does so with subtlety and finesse. Factor-in its awesome digital capabilities and the option of that upgrade power supply, and it’s all the more enticing.” Stereonet – January 2021

“Cyrus wants to prove with the i9-XR that you can also expect high-end performance from something that is a fraction of the size of a typical hi-fi device. A mission in which the British largely succeed, because small clearly does not stand for weak here. The small size has some consequences for the user comfort, such as a smaller screen (which is very rich in contrast) and a busy back panel. However, they do not detract from the core values of the Cyrus i9-XR: playing your music in high quality and in a warm, intimate way, even on Goliath speakers that are many times larger than this little David.” (Review in Dutch)

“Although the i9-XR sounds like a typical Cyrus, the overall tangibility and vividness of the sound have been improved here. This modernized aesthetic is best characterized by three simple words: timbre, power and emotion. And the fourth – resolution, because it is present here in a high measure. Therefore, with a clear conscience, I put the newly launched Cyrus i9-XR on an honorary shelf with the inscription “5/5 recommendation”!” (Review in Polish)

“This compact beauty has what it takes to scare many heavyweight competitors. In any case, you never have the feeling that you are underpowered with just 2 x 90 watts. More importantly, the i9-XR drives very good speakers with ease and this results in tonal openness and spatial transparency. The technology takes a back seat when it comes to music reproduction. The integrated HiRes DAC is excellent, as is the phono MM stage which satisfies even more demanding users. The price/performance ratio of this Brit is excellent.”

“This English amplifier is incredibly fast and accurate, without being overly exaggerated or becoming uncomfortable for the listener. For those who prefer cosy and smooth – look elsewhere. That doesn’t mean the Cyrus i9-XR cannot sound smooth, quite the opposite. But its most obvious characteristic is a fast, dynamic sound with excellent definition and clarity. Think of the most powerful version of a Mini.”

“The i9-XR remains stable with large loudspeakers and is able to drive them with courage. In addition, the amp comes with a wide range of features, including five digital inputs.”

“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.”

“The CYRUS i9-XR is the best of the best and the supreme integrated amplifier from the CYRUS product range. The i9-XR is an obvious contender for best one-box performer. Further, it challenges and may even better many of today’s state-of-the-art amplifier front ends in its ability to convey music’s emotional content. That is quite an accomplishment.”

“At this sort of money, the i9-XR is spectacularly short of
alternatives that can rival its level of insight, its
well-controlled perkiness or its out-and-out
fidelity. The addition of all those digital inputs
is a fine and sensible idea, and the quality of
its phono stage is not up for question.”
