Cyrus Audio 80 PRE Preamplifier

The Cyrus Audio 80 PRE is a full-width preamplifier that brings the BluOS streaming platform directly into the preamplifier stage of a high-performance separates system. Designed as the natural partner to the Cyrus 80 PWR power amplifier, the 80 PRE places streaming, source switching and signal handling in a single, dedicated preamplifier chassis — built to the same engineering standard and physical format as the rest of the 80 Series range.

BluOS in a Dedicated Preamplifier

The 80 PRE is the first Cyrus preamplifier to integrate BluOS natively — bringing the full capability of one of the most developed and stable streaming platforms directly into the signal chain ahead of the power amplifier. BluOS provides access to Tidal, Qobuz, Spotify, Amazon Music, and a wide range of other services, alongside locally stored music via UPnP or USB. High-resolution audio is supported, and multi-room capability is included as standard — the 80 PRE integrates seamlessly with any other BluOS-enabled product in the home without additional configuration.

The BluOS app on iOS and Android provides a consistent, well-designed control interface that has been actively developed and refined over many years. For those already running BluOS components elsewhere in the system — including the Cyrus Classic Stream — the 80 PRE fits into an existing ecosystem without friction.

Full-Width Chassis and Enhanced Power Supply

The 80 PRE benefits directly from the engineering headroom that the full-width chassis provides. In a preamplifier, power supply quality is critical — the signal levels being handled are small, and the sensitivity of the circuit to power supply noise is correspondingly high. The full-width format allows Cyrus to build an internal power supply of appropriate scale for a component at this level, without the need for the external Cyrus PSX-R2 addition that unlocked the full potential of earlier half-width designs.

Partnership with the 80 PWR

The 80 PRE is designed from the outset to partner the Cyrus 80 PWR power amplifier. Together they form the summit of the Cyrus 80 Series separates system — a preamplifier and power amplifier combination that separates signal handling from current delivery in the way that the best high-end systems have always done. The 80 PWR delivers 200 watts per channel in stereo and bridges to 300 watts in mono; the 80 PRE feeds it with the cleanest possible signal, with BluOS streaming and analogue source switching handled entirely within the preamplifier stage.

For those who want to extend the system further — adding a Cyrus 40 CD as a disc source, or building around the Cyrus 40 Series alongside the 80 PRE and 80 PWR — the 80 PRE's connectivity accommodates a complete and ambitious system architecture.

Flexibility for Separates Listeners

The 80 PRE also works in wider system configurations — partnering with power amplifiers from other manufacturers, or functioning as the preamplifier stage in a system that incorporates Cyrus 40 Series components alongside 80 Series amplification. This flexibility is deliberate. At this level, the listener's system is unlikely to consist of a single brand's components from source to speaker, and the 80 PRE is designed to operate effectively at the centre of a complex, high-performance system.

Who Is It For?

The 80 PRE is for the listener who has moved beyond the integrated amplifier format — either because their system demands more than a single chassis can deliver, or because they prefer the control and flexibility that a dedicated preamplifier provides. It suits those building or completing an 80 Series separates system with the Cyrus 80 PWR, and those who want BluOS streaming integrated directly into the preamplifier rather than added as a separate source component. Those coming from the Classic Series — whether from the Cyrus Classic AMP or a Classic Series separates configuration — will find the 80 PRE a significant step forward in both capability and ambition.

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 can demonstrate the 80 PRE in our Norwich showroom, partnered with the 80 PWR as a complete separates system, and can advise on how it fits into a wider Cyrus or mixed-brand system architecture. If you are planning a serious separates system and want to understand what the 80 Series is genuinely capable of, we would encourage you to come and hear it.
