Cyrus 40 AMP
Integrated amplifier
Relative price
typical
Among the 59 integrated 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.
What it is
CATALOG CORRECTION: power was 95W; correct = 81W/8Ω (124W/4Ω). Cyrus quotes 100W/6Ω in official spec (Cyrus convention).
Optional 40 PSU upgrade: 81W → 92W/8Ω, 124W → 144W/4Ω. New ES9039Q2M DAC + HyperStream IV.
Class AB + toroidal transformer.
Competition record
Assessed against 19 rivals across the sixty systems: 2 head-to-heads won, 58 lost.
