Compared with the obvious alternative of a basic modern budget amp, £100 is a fair price for this Denon, sitting just below the £111 median and above the £96 25th percentile from 31 comparable listings. It is not a bargain, but neither is it ambitious; a clean, fully working example at this money is sensibly priced.
The PMA-520AE remains a capable entry-level integrated: clean, balanced amplification, plenty of analogue inputs, and a useful moving-magnet phono stage for a turntable. Its roughly 45 watts per channel into 8 ohms suits most modest standmounts and easy-going floorstanders, while Source Direct keeps the signal path straightforward. With condition unspecified, confirm both channels, the phono input, selector, volume control and remote before buying; otherwise, £100 is a reasonable punt for a versatile starter system.

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.
