Denon AVR-4520 AV Receiver Hi I’m offering my excellent condition & in full working order Denon AVR-4520 AV receiver at an amazing price as it is no longer required and deserves a new home to bring joy to someone else. Must sell as its taking up valuable storage space and priced accordingly. Will consider any reasonable offers!! This unit is a beast & has not skipped a beat and in perfect condition. The sound is stunning for theatre and 2 channel music with total immersion and control. 9.2 channel (independent sub pre outs), 150W per channel, 4K support, airplay, Audyssey MultEQXT32, mono bloc
Should you jump on an AVR-4520 at A$670? Yes — against your recent comparable AUD market, that lands well below the A$1,081 25th percentile and looks like a strong deal rather than merely fair. It’s also miles under the A$1,326 median, so the price is comfortably buyer-friendly for an excellent-condition unit.
The appeal here is the kind of big, fully featured Denon flagship that still makes a lot of sense for serious home-theatre use: strong amplification, substantial connectivity, and the sort of build quality that gave this model its reputation. If it’s complete and working cleanly, the upside is clear — you’re getting a high-end receiver for entry-level money. At this price, the main checks are practical rather than red-flagged: confirm all channels work, HDMI switching is stable, and the remote/setup accessories are included.
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.
