Cyrus 80 AMP
Integrated amplifier
Relative price
above typical
Among the 59 integrated amplifiers in the catalogue, this one is above typical.
A band places a component against its peers and carries no price. It is deliberately the only price indicator on this page: a second one, measured against a different set, would narrow the two together far enough to give the figure away.
What it is
POSITIONING (2026-05-12 refresh): Designed by Cyrus Audio Ltd. under MD Nick Clarke (new ownership). Per Nick Clarke at 2025 launch: "I am very proud to present these 80 series products as the next logical evolution of the brand." Per StereoNET: Cyrus is "throwing its hat into the premium hi-fi market" and putting this range "in direct competition with the likes of Naim, Linn and Hegel." Launched November 2025.
PARTNER COMPONENTS (Cyrus 80 + 40 mix-and-match per official): 40 CD player and 40 PPA phono stage can be combined into a 80-Series system; 80 PRE pairs with 80 PWR for full separates upgrade above the 80 AMP.
EVIDENCE STATUS (as of 2026-05-12): catalogue entry has full spec data but per-component evidence audit (reviews + comparisons + pairings) has not yet reached this entry. Reviews to source when audit resumes: What Hi-Fi Bristol Hi-Fi Show 2026 coverage; StereoNET review when posted; HiFi BLOG / HomeTheaterReview launch announcements; SoundStage Australia coverage; The Listening Room US dealer commentary; Richer Sounds product description (already primary-source verified for spec data).
Competition record
