The PMA-737 is a notably capable vintage Denon: a straightforward, muscular integrated with useful MM/MC phono, around 55 watts per channel, and a strong reputation for clean, well-defined sound. At US$290, though, this is ambitious rather than a bargain: it sits exactly at the 75th-percentile asking price, versus a US$170 median and US$149 25th percentile in five recent comparables.
Its appeal is the unusually versatile feature set—MM/MC phono, multiple tape loops, speaker A/B switching, tone controls, loudness, and subsonic filtering—plus enough power for many conventional speakers. At this money, condition needs to be demonstrably excellent: clean operation across every input, quiet controls, reliable speaker-relay engagement, and ideally service history or original-owner provenance. Without those extras, I’d look for a tested example closer to the median.
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.
