Compared with the obvious move of buying a newer budget integrated amp, £65 for this Denon looks fair and slightly on the friendly side of market. Against the recent GBP comps, it sits just above the £61 median and within the £55–£64 typical band, so this is not a bargain-bin score but also not an inflated ask.
What makes it worth a look is the PMA-707’s reputation for solid, straightforward amplification: clean, punchy, and very usable with efficient speakers or a modest vintage system. If it’s genuinely tidy and unmolested, the value is in getting a well-built old-school amp at sensible money. At this price, the main checks are simple: confirm all inputs work, the volume and selector controls are quiet, and the unit has been reasonably cared 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.
