Pros
Clear, detailed and musically refined sound with impressive rhythmic drive and dynamic expression.
Strong, articulate bass and confident speaker control despite the compact half-width chassis.
Excellent connectivity, including HDMI eARC, USB DAC, MM phono stage and a well-regarded headphone output.
Cons
The optional 40 PSU delivers a meaningful upgrade but is expensive.
At extreme volume levels, composure and bass control can diminish with demanding speakers.
The display does not show incoming signal resolution, and the control software is not as slick as some rivals.

What Reviewers Are Saying
SOUND QUALITY PERFORMANCE 93/100
The 40 AMP is widely praised for combining clarity, speed and control with a refined, musically engaging balance. Its presentation is open and stable rather than exaggerated, with strong bass authority, convincing tonal colour and an expansive sense of space.
Transparency Resolution
94/100
What Hi-Fi? found the Cyrus unusually clear and articulate, with a clean, detailed performance that reveals recording shortcomings without overstating them. StereoNET likewise heard extra transparency, a detailed midband and smooth, delicate treble, while Pursuit Perfect System noted a notably clean and see-through quality.
Tonal Balance Musicality
93/100
What Hi-Fi? describes an essentially neutral and refined balance that successfully joins analysis with enjoyment, while Sound Advice calls its tonal realism and refinement especially convincing. Other listening reports hear a touch of warmth, full and pleasing vocals, and smooth treble, though the slightly forward character may suit some speaker pairings better than others.
Dynamics
93/100
Reviewers consistently praise the amplifier's agile, expressive delivery, its handling of musical contrasts and its ability to drive demanding loudspeakers without apparent strain. Sound Advice found it effortless with complex, fast material and current-hungry Kudos Titans; at extreme volume levels, Pursuit Perfect System heard some loss of composure and bass control.
Soundstage Imaging
92/100
What Hi-Fi? found the imaging impressively focused and stable, even if the stage was not the broadest encountered. StereoNET heard a satisfyingly deep and impressively wide presentation, while Sound Advice praised the air and convincing space around performers; the PSU upgrade is reported to enlarge the stage further.
Assessments of Build Quality, Usability, and Overall Propositions.
Build Quality
91/100
Reviewers describe a well-made compact chassis with brushed or anodised aluminium, a glass fascia and a crisp full-colour display. Sound Advice calls it extremely well made and easy to accommodate, while StereoNET notes quality-feeling details including the remote, though it found the volume control positive rather than silky smooth.
Features Connectivity
95/100
The 40 AMP is unusually comprehensive for a compact integrated: four analogue inputs, MM phono, preamp and fixed outputs, headphone output, USB-B, optical and coaxial digital connections, HDMI eARC, and a high-resolution ESS DAC. Reviewers also praise the improved five-inch display and the capable phono stage, although its Ethernet and USB-A connections are for updates and control rather than network streaming.
Value for Money
92/100
At around £3,995, What Hi-Fi? calls it the best all-rounder it can think of for the money despite strong competition. Sound Advice considers its bass authority comparable with hard-hitting rivals at this price, while Pursuit Perfect System sees substantial capability in the small enclosure, albeit without identifying one single area in which it dominates every rival.

Manufacturer's Description — Cyrus Audio
Whether you are a digital or analogue fan, the 40 AMP was designed to be at the centre of your home audio and provide the perfect partner regardless of your preferred playback source. Delivering the level of exceptional performance expected from today’s music fans, this integrated amplifier has the capabilities to drive even the most demanding of loudspeakers. With 100 watts per channel into 6 ohms, and a generously over-specified power supply the 40 AMP is capable of reproducing the scale and drama of the musical performance in your own home.
Encased in the sleek design of the 40 series aluminium casing with a 5” hi-resolution full colour TFT display, the 40 AMP has been designed to fit into today’s modern lifestyle. Sitting at the centre of this multi-functional amplifier is an electronic circuit that has been designed entirely by the R&D team at Cyrus. The DAC is based upon the latest chipset from ESS, the ES9039Q2M, and has been reworked to provide an audio signal that replicates the artists original recording to a level not seen in a Cyrus product before.
As well as multiple digital and analogue connections, the 40 AMP has a low noise MM phono stage which inherits many of its design features from the award-winning Classic PHONO. The phono stage performs at a level way above its class, featuring low background noise and high dynamic range, providing the perfect complement for a quality vinyl turntable.
The features of the 40 AMP do not stop with your love of music, now with the addition of the latest HDMI eARC input, your home audio now provides the opportunity to enjoy your favourite films or tv series through your chosen loudspeakers, putting the 40 AMP well and truly at the centre of your home entertainment.
Customised DAC design is at the forefront of all digital products from Cyrus, and the 40 AMP embodies this approach like never before.
Based upon the ESS Sabre ES9039Q2M chipset and HyperStream IV Dual DAC technology, the 40 AMP supports up to 32-bit 768kHz PCM & DSD1024 audio files. Every component has been analysed by our engineering team and the board layout fully optimised to tune the DAC so that we can achieve the highest possible performance.
As well as multiple digital and analogue connections, the 40 AMP has a low noise MM phono stage which inherits many of its design features from the award-winning Classic PHONO. This phono stage performs at a level way above its class, featuring low background noise and high dynamic range, providing the perfect complement for any quality vinyl turntable source.
The wideband power amplifier of the 40 AMP 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 40 AMP power amplifier is very capable of reproducing the scale and drama of the musical performance.
Even when the 40 AMP is packaged with our latest custom designed switch mode power supply, improvements are always possible. To further enhance the experience and provide the 40 AMP with the best configuration of power, you can easily connect the 40 PSU external power supply to the 40 AMP with a single cable. Providing multiple supplies, all of the output voltages from the 40 PSU are digitally controlled internally, so are extremely stable and virtually noise free.
