Classic AMP

This integrated amplifier provides a significant step up in performance from previous versions by using everything 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.

Analog 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.

Amplifier Power

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.

MM Phono Input

The phono MM input stage design features dual active gain stages and passive RIAA equalisation

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 Port

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.
