Condition is unknown, so £100 lands a bit above the current used sweet spot for this amp: with 23 recent GBP comparables, the median is £59 and the 75th percentile is £80, so this is priced ambitiously rather than as a bargain. It is not wildly out of line if it is exceptionally clean, fully working, and comes with the right extras, but it does need stronger condition proof than a typical fair-price listing.
The PMA-250SE is a well-liked, no-nonsense integrated that suits a straightforward, musical system and has enough pedigree to stay desirable on the used market. If the unit is tidy, quiet, and has been cared for by an owner who can show service history, that adds real value; otherwise, at this asking price, buyers should be looking closely at channel balance, scratchy controls, relay noise, and whether the fascia, knobs, and remote are complete.
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.
