Cyrus Stereo 200 (EOL — channel clearance)

Power amplifier

Relative price

below typical

Among the 25 power amplifiers in the catalogue, this one is below 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

Cyrus stereo Class D power amplifier in half-width form factor; matches Pre-XR aesthetically. Designed Huntingdon UK.

I/O: both RCA and XLR inputs accepted — versatile partnering. Class D efficiency means runs cool and has compact form.

Spec coverage low (some Cyrus datasheet details not published in plain reviews); Stage 1.5-style spec capture deferred.

Competition record

Assessed against 19 rivals across the sixty systems: 4 head-to-heads won, 56 lost.

Where it gives ground

The dimension the engine names as the weakest link, counted across every head-to-head it lost.

  • quietness at rest ×19
  • vocal presence ×19
  • low-level clarity ×9
  • timing and drive ×6
  • midrange truth ×3
