At £90, this sits well above the local used market for the Denon: with recent comparable GBP listings centered at £53 and the upper quartile at £61, it reads as ambitious rather than fair. For a buyer, that means you’d want either unusually strong condition, proof of servicing, or some included extras to justify the gap; otherwise, it is a stretch versus the typical asking range.
That said, this is a respected late-era Denon integrated, and the PMA-250III is the kind of amp people buy for its straightforward, clean presentation and solid day-to-day practicality. If it’s genuinely tidy, fully working, and unmolested internally, there is value in a well-kept example—but at this price the listing should be especially complete and confidence-inspiring, because you’re paying a premium over what comparable examples are usually advertised for.

Denon traces its origins to 1910, when American entrepreneur Frederick Whitney Horn founded Japan's first audio equipment company, Nipponophone, initially focused on gramophones and records. The Denon brand emerged in 1939 from the merger of Japan Denki Onkyo—combining "den" for electricity and "on" for sound—with other entities, marking a shift toward professional audio development. This heritage includes pioneering Japan's first professional disc recorder in 1945, used to capture Emperor Hirohito's voice, and launching the nation's first long-playing records in 1951.
The brand excels across a broad spectrum of hi-fi categories, from amplifiers, turntables, and tuners to loudspeakers, cassette decks, and phono cartridges. Denon's innovations extend to digital frontiers, such as the world's first practical PCM recorder in the early 1970s, the inaugural CD player in 1981, and early home theater systems with Dolby Digital in 1995. Today, its lineup encompasses AV receivers, headphones, wireless streaming solutions like HEOS, and high-channel processors, blending professional-grade components with consumer accessibility.
Denon holds a commanding position as a mid-to-high-end mainstay in the hi-fi market, revered for its blend of technological firsts, robust build quality, and balanced sound signatures that appeal to discerning enthusiasts. No longer a vintage collector's niche, it competes confidently against premium rivals, backed by over a century of audio leadership and strategic partnerships like its merger with Marantz.
