Cyrus Audio 80 AMP

The Cyrus Audio 80 AMP is a full-width integrated streaming amplifier delivering 150 watts per channel in class A/B configuration. It brings together Cyrus's most capable amplifier engineering with the BluOS streaming platform — creating a single, self-contained unit that handles everything from network streaming to loudspeaker drive with no compromise on performance.

The 80 AMP marks a significant step forward for Cyrus. The full-width chassis — a departure from the compact half-width format the brand is known for — allows the engineering team to incorporate an internal power supply of a scale previously only available externally. Where earlier Cyrus amplifiers benefited from the optional Cyrus PSX-R2 external power supply, the 80 AMP builds equivalent supply capacity directly into the product. The result is a lower noise floor, greater dynamic headroom, and the authority needed to drive a wide range of loudspeakers with confidence.

BluOS Streaming at the Core

BluOS is one of the most capable and mature streaming platforms available, offering access to high-resolution audio up to 24-bit/192kHz, lossless streaming, and a wide catalogue of services including Tidal, Qobuz, Spotify, and Amazon Music. The 80 AMP integrates BluOS natively, meaning the streaming engine is not an afterthought — it is built into the architecture of the amplifier from the ground up.

Multi-room capability is included as standard. If you run other BluOS-enabled products in your home, the 80 AMP joins that ecosystem seamlessly.

Amplifier Performance

At 150 watts per channel, the 80 AMP has the power to control demanding loudspeakers with ease. Cyrus's class A/B amplifier topology prioritises accuracy, timing, and low distortion — qualities that define the Cyrus house sound across the range. The generous internal power supply ensures that headroom is available when the music demands it, without the compression that can afflict less well-specified designs.

Part of the Cyrus 80 Series

The 80 AMP integrates naturally with other products in the Cyrus range. The Cyrus 40 CD connects cleanly for those who prefer physical media alongside streaming, and the Cyrus 40 PSU can be used to further optimise supporting components in your system. Those coming from the Classic range will find the Cyrus Classic AMP and Cyrus Classic Stream useful reference points for understanding how significantly the 80 series raises the bar.

Technical Specifications

Who Is It For?

The 80 AMP is aimed at the serious listener who wants a single, high-performance unit capable of handling every source through one box. If you value timing, control, and dynamic authority — and want BluOS's flexibility without sacrificing amplifier quality — this is a compelling proposition. It suits those moving up from separates who want to simplify without stepping down, and those building a system around streaming who refuse to compromise on the amplifier stage.
