The AVC-X4700H sits in a strong spot in Denon’s lineup: it’s a well-liked, feature-rich AVR with plenty of processing muscle for serious home cinema setups. At £698, this looks like a bargain versus the recent used market, sitting below the £756 25th percentile and well under the £839 median, so the asking price has real value on its side.
What makes it worth chasing is the usual Denon appeal: solid amplification, broad format support, and the kind of upgrade headroom that still makes these receivers desirable for 4K/immersive systems. If the unit is clean, fully working, and comes with the original remote and calibration mic, that adds to the upside; at this price, I’d be more concerned with proof of stable operation than with haggling.

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.
