Compared with buying a new power supply, £140 for this Cyrus unit looks like a strong bargain in the used market. Against the recent GBP comps, it sits well below the £188 25th percentile and far under the £289 median, so this is priced to move rather than priced on optimism.
That makes it an easy one to like if you’re already in the Cyrus ecosystem: these PSX units are valued for cleaner, more effortless drive and better low-level control than the stock supply. At this price, the main upside is simply getting a respected upgrade piece for little outlay, so the key checks are straightforward—confirm it powers up properly, the connector is right for your amplifier, and the accessory set is complete.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
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.
