US$77 looks like a solid buy, sitting around the low end of the used range for this model rather than anywhere near ambitious. Recent market snapshots show one sale at US$53 and another at US$134, which puts this asking price comfortably in the sensible zone; for a clean, working unit it’s fair to slightly favorable.
What makes it worthwhile is that this was a well-liked early HDMI-era Denon: 7.1-channel power, useful surround flexibility, and Denon’s usual reputation for straightforward setup and dependable sound. It’s a good pickup for a second system or a budget theater build, especially if the remote is included and the HDMI passthrough still works properly. At this age, just make sure it powers up cleanly, switches inputs correctly, and isn’t missing the remote or calibration mic.

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.
