Power amplifier
typical
Among the 25 power amplifiers in the catalogue, this one is 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.
POWER SPEC CANONICALISATION (lesson #14c): All primary sources EXCEPT What Hi-Fi Bristol Show 2026 confirm 200W/ch into 8Ω stereo (HiFi BLOG, HomeTheaterReview, SoundStage Australia, StereoNET, The Listening Room US dealer, official launch press). The What Hi-Fi Bristol Show 2026 article ("80 AMP and PWR both producing 150 watts per channel into 8 ohms") appears to be a journalist transcription error since (a) 80 AMP's 150W/8Ω is independently confirmed by Richer Sounds spec, but (b) the 80 PWR's 200W/8Ω is consistent across all other primary sources. The 80 PWR rating is HIGHER than the 80 AMP because the PWR uses chassis space otherwise occupied by 80 AMP's streaming/DAC/preamp sections for additional PSU + output stage capability — a design logic Cyrus has explicitly invoked in launch materials.
VINYL-ONLY FIT: As a pure power amplifier the 80 PWR is phono-stage-agnostic — any preamp with built-in MM/MC phono or external phono stage can feed it. Natural pairings: Cyrus 80 PRE (built-in MM/MC); Cyrus Pre-XR (built-in MM phono, streaming DAC); Naim NSC 222 (built-in MM phono); valve preamps with phono via XLR/RCA output. The 200W/8Ω power rating exceeds the needs of most cavity-eligible speakers (typically 25-150W required) so the 80 PWR carries comfortable dynamic headroom for transient peaks.
EVIDENCE STATUS: catalogue entry has launch-announcement-level spec data; per-component evidence audit (full reviews + comparisons + pairings) has not reached this entry. Reviews to source when audit resumes (post-launch listings expected late 2025 / 2026): What Hi-Fi Bristol Show 2026 + post-show review when posted; StereoNET; AVForums Ed Selley; HiFi News / Hi-Fi Choice / Hi-Fi+; TrustedReviews; The Ear; Stereophile when imported to US.
SPEC CAVEATS (lesson #14c): Cyrus has not published a full spec sheet for the 80 PWR as of verification date 2026-05-12. INFERRED fields: input impedance, sensitivity, gain, damping, 4Ω power, burst peak, dimensions. UPDATE TO VERIFY when Cyrus official 80 PWR product page posts full specifications.

Against the Anchored brief, the Longdog Audio P6100M Biamp 2x2 (4 units) keeps the slot decisively.
With the Emmae Reginae (custom), the pairing gives up most on bass control.
With the Audiolab 9000Q, the pairing gives up most on quietness at rest.
On its own merits the Cyrus 80 PWR is the weaker power amplifier for that brief.

Against the Characterful brief, the NVA S80 Stereo keeps the slot decisively.
With the NVA P50 MKII, the pairing gives up most on vocal presence.
On its own merits the Cyrus 80 PWR is the stronger power amplifier — but it loses here on fit: the pairing with the NVA P50 MKII gives up vocal presence under the Characterful weighting.
It sits well above the share of the budget this brief aims at the power amplifier position.
