Cyrus Audio 80 AMP

The Cyrus Audio 80 AMP is a full-width integrated streaming amplifier — a single, self-contained unit that combines 150 watts per channel of class A/B amplification with the BluOS streaming platform in one substantial chassis. It represents a fundamental departure from the compact half-width format that defined Cyrus for decades, and that departure is not cosmetic. The full-width chassis allows an internal power supply of a scale previously only available through the addition of an external unit — delivering the dynamic headroom, noise floor, and loudspeaker control that serious amplification demands.

A New Chassis, A New Standard

Earlier Cyrus amplifiers benefited significantly from the optional external power supply — the Cyrus PSX-R2 being the established route to unlocking their full potential. The 80 AMP builds equivalent supply capacity directly into its architecture. The result is an amplifier that arrives at its full capability without supplementary hardware — lower noise floor, greater dynamic headroom, and the authority to drive a wide range of loudspeakers with confidence from the outset.

BluOS Streaming at the Core

The 80 AMP integrates BluOS natively — not as a bolt-on streaming board, but as a core part of the component's architecture. BluOS provides access to Tidal, Qobuz, Spotify, Amazon Music, and a wide catalogue of other services, alongside locally stored music via UPnP or USB. High-resolution audio up to 24-bit/192kHz is supported, and lossless streaming from Tidal and Qobuz is handled without compromise. The BluOS app on iOS and Android provides a well-designed, stable control interface that has been refined over many years of active development.

Multi-room capability is included as standard. The 80 AMP integrates seamlessly with any other BluOS-enabled product in the home, allowing synchronised or independent zone operation without additional configuration.

Amplifier Performance

At 150 watts per channel in class A/B configuration, the 80 AMP has the power and authority to control demanding loudspeakers with ease. Cyrus's amplifier topology prioritises timing accuracy, low distortion and low-level resolution — the qualities that have defined the Cyrus house sound across four decades of development. The generous internal power supply ensures that dynamic headroom is available when the music demands it, without the compression or hardening that afflicts less well-specified designs at high output levels.

Part of the Cyrus 80 Series

The 80 AMP sits at the heart of the Cyrus 80 Series — a range designed from the ground up around the full-width chassis and the engineering headroom it provides. Those coming to the 80 Series from the Classic range will find the step forward in authority and resolution immediately apparent. The Cyrus Classic AMP and Cyrus Classic Stream are the natural reference points for understanding how significantly the 80 Series raises the performance bar.

Technical Specifications

Who Is It For?

The 80 AMP is for the serious listener who wants a single, high-performance unit capable of handling every source through one box — without any compromise on the amplifier stage. It suits those who value timing, control and dynamic authority, and who want BluOS's flexibility built in rather than added externally. It is a compelling proposition for those moving up from a Classic Series system who want to simplify without stepping down, and for those building around streaming from the outset who will not accept a lesser amplifier as the price of convenience.

Buying from Martins Hi-Fi

Martins Hi-Fi has been in Norwich since 1968. Elizabeth Gould runs the business today, and we stock only brands we have heard properly and stand behind. Dave and Chris know the Cyrus range intimately and can demonstrate the 80 AMP in our Norwich showroom across a range of loudspeakers — including direct comparison with the Classic Series if that is a question you want answered before committing. If you are planning a full 80 Series system, we can help you build it in the right order.
