At £399, this used Cyrus ONE is a genuine bargain compared to the obvious alternative of buying new or paying typical vintage rates, sitting well below the £453 75th percentile and comfortably under the £330 median from your 13 recent GBP comparables. With the 25th percentile at £126, this £399 asking price lands in the sweet spot between fair and strong deal territory—actually, it’s just above the median but still solid value given the unit’s reputation.

Cyrus Audio: Heritage and Philosophy
Cyrus Audio emerged in 1984 as a specialist electronics brand spun off from loudspeaker manufacturer Mission, with the goal of creating amplifiers to complement Mission speakers. Founded under the direction of Peter Bartlett, a veteran from NAD, the company established its identity with the Cyrus One integrated amplifier—a half-width design featuring the distinctive "control lip" that remains iconic in audiophile circles today. The brand quickly positioned itself as a pioneer in compact, high-performance audio, and later became one of the first manufacturers to champion the Compact Disc format through its partnership with Philips in the early 1980s. After separating from Mission in the 1990s, Bartlett returned Cyrus to private ownership, where it remains independently operated from its Cambridgeshire headquarters.
Cyrus has maintained unwavering focus as a two-channel hi-fi specialist, eschewing multiroom or surround formats. The company's product portfolio centers on integrated amplifiers, power amplifiers, CD players, digital-to-analog converters, and power supplies—all engineered around the principle of delivering high-end sound quality in compact form factors. The brand also pioneered networked audio, developing early high-performance music servers that demonstrated premium sound could be achieved in convenient, integrated packages.
Today, Cyrus occupies a distinctive position as a boutique, high-end British manufacturer that prioritizes sonic excellence and longevity over market size. Under current CEO Nick Clarke, the company continues evolving its Classic series—refined continuously since 1983—and the XR series, developed from scratch using cutting-edge DAC technology and UK manufacturing. Cyrus products consistently earn critical acclaim and industry awards, appealing to discerning audiophiles who value British engineering, meticulous design, and uncompromising sound quality over mass-market accessibility.
