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.
The Cyrus Classic POWER amplifier stands as the robust counterpart to complement the pre-amp's refined capabilities.
Empowering Auditory Pleasure
Tailored to harmonize seamlessly with the Cyrus Classic PRE, yet equally remarkable with diverse devices, the Cyrus Classic POWER amplifier embodies remarkable strength. Boasting 87 watts per channel with 8-ohm speakers and up to 144 watts with 4-ohm speakers, it effortlessly reserves power to gracefully fill expansive spaces with sound. Its remarkably low distortion levels ensure a clean power delivery, rendering lifelike details even at elevated volume levels.
Cyrus's Distinctive Sonic Identity
While the Classic POWER exhibits a robust and commanding sound when needed, Cyrus upholds its reputation for precision and detail. Meticulously handcrafted in the UK, the Classic POWER reflects Cyrus's unwavering commitment to detail. Nestled within its high-quality casing are an oversized toroidal mains transformer and high-output capacitors. This, combined with a short signal path circuitry, delivers the quintessential Cyrus sound—dynamic, precise, and faithfully reproducing every subtle nuance.
Studio-Quality Connectivity with XLR Precision
In addition to conventional RCA phono inputs, the Classic POWER features balanced XLR connections. Utilise these with a compatible Cyrus pre-amp, such as the Classic PRE or even the Pre-XR, for a studio-quality, ultra-low noise connection. Balanced cables effectively isolate external noise, ensuring a clearer signal—particularly over extended lengths.
Elevate with the PSX-R2 Upgrade
Recognizing the profound impact of power supplies on overall sound quality, Cyrus presents the PSX-R2 as a plug-in upgrade for the Classic POWER and various other Cyrus products. Employing a substantial toroidal transformer and audiophile-grade capacitors, the PSX-R2 provides the Classic POWER with a smooth, stable power feed, unveiling fine details and musical subtleties otherwise obscured.
Uniquely Cyrus in Design and Quality
The unmistakable Cyrus casing imparts numerous advantages over traditional hi-fi designs. The classic, die-cast casing exudes solidity, robustly resisting both electrical and mechanical interference from external sources. Integrated heat sink vents discreetly maintain optimal temperature, blending functionality with style. In terms of practicality, Cyrus is a space-efficient solution, with two units occupying the footprint of one on most hi-fi shelves.
Elevate your auditory experience with the Cyrus Classic POWER amplifier – a blend of enduring design, precision engineering, and timeless sonic excellence.
