This looks like a seller’s market for this amp: at £157, it sits well above the £61 75th percentile and more than double the £56 median, so the asking price is ambitious rather than fair. Even allowing for the model’s vintage Denon appeal and the fact that these can still sound lively and controlled, this is not a bargain at current comparables.
The upside here is that it’s a respected integrated with a solid reputation for musical, punchy presentation and enough power for sensible bookshelf or efficient floorstanders. If the unit is genuinely clean, fully working, and ideally comes with the original remote or other extras, that helps the case a bit, but not enough to erase the premium. I’d only bite if the condition is exceptional and the seller can prove recent service or standout provenance.
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.
