Cyrus Audio Classic AMP
The Cyrus Classic AMP brings open, spacious imaging and crisp detail to a compact Class A/B design, revealing texture, nuanced vocals and tightly organised mixes. What Hi-Fi? also found its phono, digital and headphone stages consistently expressive, while the optional PSX-R2 promises greater scale and control. With MM phono and four digital inputs, it is a polished mixed-source hub.

Pros
Clean, agile and highly detailed presentation, with strong control of transients and bass lines.
Open, spacious, layered soundstage with crisp, stable imaging under demanding material.
Well-equipped for mixed systems: capable MM phono stage, optical/coaxial DAC inputs and an expressive headphone stage.
Compact, solidly built chassis with meaningful PSX-R2 power-supply upgrade potential.
Cons
Falls short of leading rivals for outright dynamic muscle, rhythmic momentum and large-scale authority.
Rear-mounted 3.5mm headphone socket is awkward to access.
No USB input or DSD support; its leaner balance benefits from careful speaker matching.

What Reviewers Are Saying
SOUND QUALITY PERFORMANCE 91/100
Reviewers find the Classic AMP notably open, detailed and well organised, combining a rich-leaning midrange with controlled bass and crisp imaging. Its presentation is agile and punchy, though it stops short of the outright dynamic authority and rhythmic excitement of leading rivals such as the Rega Elex Mk4 and Naim Nait XS 3.
Transparency Resolution
92/100
What Hi-Fi praises its clarity, crisp detail and ability to uncover instrumental texture within dense productions. Hifi Pig similarly calls it clean and detailed, while Like Hifi highlights its sensitivity, finely balanced presentation and attention to small musical details.
Tonal Balance Musicality
91/100
The tonal character is described as honest, finely balanced and slightly rich through the midrange rather than overtly warm or coloured. Reviewers also note sonorous, controlled bass, nuanced vocals and a sweet, non-aggressive presentation that remains involving across varied music.
Dynamics
88/100
The Cyrus handles transients, crescendos and bass lines with good punch, agility and composure; Hifi Pig found its dynamic swings especially engaging. What Hi-Fi adds an important qualification: while it is controlled and surprisingly forceful on crescendos, it lacks some of the muscular authority, momentum and enthusiasm offered by class-leading competitors.
Soundstage Imaging
92/100
Reviewers consistently hear an open, spacious and well-layered stereo picture, with focused and stable images even as material becomes demanding. Hifi Pig reports sound extending beyond the speaker positions, while Like Hifi describes a richly three-dimensional impression with instruments clearly arranged in space.
Assessments of Build Quality, Usability, and Overall Propositions.
Build Quality
89/100
The compact aluminium and magnesium-alloy casework is reported to feel solid, while Like Hifi found the connections rock-solidly mounted. Internal engineering is also unusually thorough, including a generously specified transformer, separated supply arrangements and a symmetrical layout intended to minimise interference.
Features Connectivity
91/100
The Classic AMP covers most conventional hi-fi needs with four analogue inputs, MM phono, a capable QXR DAC, two optical and two coaxial digital inputs, pre-out and a headphone output. The phono and headphone stages are both positively reviewed, but there is no USB input or DSD support, and the rear-mounted 3.5mm headphone socket is inconvenient to access.
Value for Money
88/100
At roughly €2,395, reviewers regard the Classic AMP as an attractive proposition thanks to its compact form, upgrade path, phono stage, DAC and broad sonic capability. Hifi Pig considers it well priced for its sound, build and included facilities, although What Hi-Fi notes that it faces strong competition from similarly priced alternatives.

Manufacturer's Description — Cyrus Audio
The Classic AMP is the latest update to an integrated amplifier that has been part of the Cyrus product range for over a decade.
This integrated amplifier provides a significant step up in performance from previous versions by using everything that we learnt when developing the fantastic XR Series, but retaining the familiar design of the Classic series. The circuit design has been completely re-designed and the majority of the internal components have been upgraded by the Cyrus R&D team, which has resulted in sound improvements that will help the Classic series retain a loyal fan base for years to come.
The power amplifier delivers 91W per channel into 6Ω. The wideband design responds from D.C. to beyond 50kHz to ensure a flat frequency response and minimal phase shift through the audio band.
The analogue preamp features relay input selection for the five analogue inputs and a precision gain control for volume. The design is intentionally wide bandwidth.
The power supply includes a 304VA toroidal power transformer delivering power to a high capacity power supply reserve. The preamplifier power supply is electrically separated from the power amplifier and driven from its own transformer winding. Digital control circuits are assigned a separate mains power supply, completely isolated from the signal circuitry.
The Classic AMP includes a port for the PSX-R power supply. Power from the PSX-R is routed internally to the analogue stages of the preamplifier to provide a more stable, low-noise power supply for the analogue preamp and post-DAC stages of the D/A converter.
