Cyrus Classic PRE + Cyrus Classic POWER Bundle
Cyrus Classic PRE
This preamplifier 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.
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.
Un/Balanced Outputs
The unbalanced outputs are provided for close wired systems where the power amplifier is located close to the Classic Pre. The balanced outputs are recommended for longer cable runs in systems where the Classic Pre is driving power amplifiers placed close to the system speakers or active speakers.
Power Supply
The Classic Pre power supply includes a 74VA toroidal power transformer delivering power to a high capacity power supply reserve. Within the circuit design, a total of 11 independent power supply regulators regulate, then sub-regulate quiet power. Digital control circuits are assigned a separate mains power supply, completely isolated from the signal circuitry.
PSX-R
The Classic Pre 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.
Phono MM
Input The phono MM input stage design features dual active gain stages and passive RIAA equalisation.

Product Objective
The Classic POWER is the latest power amplifier within the familiar Classic range. The objective was to create 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 topology 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.
Features and benefits Connectivity
Unbalanced (RCA) inputs (with daisy-chain out)
Balanced (XLR) inputs
12V trigger input
MC-BUS connection (control integration with Cyrus system) PSX-R2 upgrade connection
Firmware upgrade port
Power Amplifier
The wideband power amplifier of the Classic POWER responds from D.C. to beyond 50kHz ensuring ruler flat frequency response and keeping any undesirable phase shifts out of the audio band. With a generous, over-specified power supply the Classic POWER power amplifier is very capable of reproducing the scale and drama of the musical performance.
High capacity power supply
The power supply includes a massive 408VA toroidal power transformer delivering power to a high capacity power supply.
PSX-R2 port
The Classic Power includes a port for the PSX-R2 power supply. Power from the PSX-R2 is routed internally to the voltage amplifier stage of the Classic POWER to provide a more stable, low-noise power supply to this key part of the amplifier.
Low power standby consumption
The Classic POWER can be remotely switched to and from a low consumption standby mode via MC-BUS or using the 12V trigger input.
