Cyrus Classic Amp Half-chassis Integrated Amplifier

Cyrus Classic Amp Integrated Amplifier - Cyrus

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.

Power Amplifier
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.

Analogue Preamplifier
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.

Power Supply
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.

PSX-R
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.
