A fair price, sitting just above the typical midpoint rather than looking like a bargain. Your comparable listings put the median at £60 GBP, with the middle 50% running from £51 GBP to £71 GBP, so £63 GBP is entirely reasonable—provided it is tested and complete.
The PMA-255UK is a capable, unfussy budget integrated with a surprisingly punchy 30 watts per channel, good bass drive, four line inputs, and a useful headphone output. It suits an efficient-speaker system well and has the direct, articulate presentation often associated with this generation of Denon amplifiers. Check that both channels are clean, the controls are quiet, and the speaker terminals and input sockets are sound; there is no phono stage, so a turntable needs a separate phono preamp.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
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.
