This is a buyer’s market for this amp at the moment: at £105, it sits below the £108 25th percentile and under the £112 median from your recent GBP comps, so it reads as a solid deal rather than merely fair. It is not a fire-sale bargain, but it is priced attractively enough that a clean, working example should move quickly.
The PMA-655R is well thought of for its stable, punchy integrated sound, sensible power on tap, and the sort of straightforward Denon build that tends to be easy to live with. At this level, the upside is getting a respected older integrated without paying top-of-market money; just confirm basic functionality, selector pots, and that any remote or manual is included if that matters to you.

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.
