Cyrus Audio

Founded in 1984 with the launch of the iconic Cyrus One amplifier, Cyrus Audio has remained an independent British brand devoted to precision audio engineering. Unlike many competitors, Cyrus continues to design, assemble, and manufacture all of its products in the UK, maintaining the prestigious Made in Britain label.

Cutting-Edge Modularity Across Classic, XR & 40 Series

Cyrus offers a comprehensive range of modular Hi-Fi components across three main product lines:

Classic Series: A refreshed take on the original Cyrus design, updated since 2022.

XR Series: A performance step up with improved power supplies and circuit refinement.

40 Series: The new high-end reference range featuring minimalist aesthetics, full modularity, and premium materials.

Key models include the 40 AMP integrated amplifier, 40 ST BluOS streamer, 40 CD transport, and the 40 PSU external power supply—all built in compact, signature “half-width” enclosures that save space without sacrificing performance.

Signature Technologies That Define Cyrus

Zero Feedback topology: Reduces global feedback for superior transparency and musicality. Featured in high-end power amps like the Mono X 300 Signature (319 W @ 6 Ω).

Linear and toroidal power supplies: For ultra-clean, stable current delivery.

Proprietary CD servo system: Ensures precise disc reading and reduced jitter.

Quick Streaming with BluOS: Built-in high-resolution streaming with intuitive multi-room support.

Stackable external PSUs: Cyrus’s PSX‑R and PSU‑XR power supplies can boost dynamic performance by up to 60%, offloading internal circuits for better clarity and control.

Frequently Asked Questions About Cyrus Audio:

Where are Cyrus products made?

All Cyrus devices are designed in Huntingdon, Cambridgeshire, and assembled in Nottingham by SMS Electronics, proudly bearing the Made in Britain hallmark.

What are the differences between the Classic, XR, and 40 Series?

Classic: Entry-level for audiophiles, with a clean new look since 2022.

XR: Mid-range with significant sonic and technical upgrades.

40 Series: The premium flagship series offering top-tier performance, sleek design, and full modularity.

Why use external power supplies like PSX‑R or PSU‑XR?

These external units deliver cleaner, higher-current power, dramatically enhancing resolution, headroom, and dynamics in compatible Cyrus gear—up to 60% more performance in some setups.

What is the benefit of Zero Feedback circuitry?

It avoids traditional global negative feedback loops, resulting in greater sonic transparency, improved imaging, and a more natural soundstage—ideal for discerning listeners.

Are Cyrus systems modular and scalable?

Absolutely. Cyrus Audio is built for long-term system growth—you can stack components across the Classic, XR, and 40 lines, adding streamers, phono stages, transports, and external PSUs as needed.

Cyrus Audio combines British craftsmanship, cutting-edge circuitry, and flexible modularity to deliver audiophile-grade performance in a compact, future-proof format.
