The PMA-350 sits in that solid Denon integrated sweet spot: sensible power, good build, and the kind of straightforward, musical presentation that keeps these older amps in demand. At £90, this is a touch above the £69 median and right at the £90 75th percentile, so it reads as fair-to-ambitious rather than a bargain.
What makes it worth a look is the usual Denon strengths: dependable everyday performance, decent drive for normal speakers, and enough vintage appeal to be satisfying without being fussy. If it’s clean, fully working, and hasn’t had scratchy controls or channel dropouts, it can still be a very good buy at this level; ideally, you’d want clear proof of service history or a recent test, since that matters more than cosmetics on an amp of this age.

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.
