Cyrus 40 PPA Power Amplifier
Compact Power With Purposeful Design
The Cyrus 40 PPA is a compact power amplifier engineered for music lovers who want a dedicated amplification stage that excels in control, clarity and dynamic response. Designed and built in the UK as part of the Cyrus 40 Series, it embodies Cyrus’ long-standing philosophy of engineering sound first, features second.
Unlike amplifiers that chase big numbers, the 40 PPA focuses on how power is delivered and controlled. It gives speakers the stability and authority they need to perform with poise, whether you’re listening to delicate acoustic pieces or full orchestral recordings.
The result is sound that feels articulate, transparent and refined across a wide range of genres.
Power With Control, Not Hype
Rather than flaunting inflated wattage figures, the 40 PPA emphasises useful, controllable power delivery. The design is optimised for clean current delivery and load stability, so the amplifier remains composed with complex music passages and varying speaker impedance loads.
This makes it a superb partner for precision-oriented systems where speed, timing and musical coherence matter as much as brute force.
Designed for System Building
The 40 PPA fits cleanly into systems built around Cyrus preamplifiers, integrated amplifiers or digital sources. Its compact size and disciplined engineering make it easy to place in traditional hi-fi racks or modern media units without compromising performance.
Cyrus’ approach to grounding, power supply design and chassis rigidity all contribute to a quiet, stable foundation for any high-fidelity system.
