The Classic POWER is the latest power amplifier within the familiar Classic range. Cyrus's objective was to create a significant step up in performance from previous versions by using everything that they 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.
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.
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.
