Our Thoughts RADAR AI

This is a buyer’s market for value seekers, and at A$175 the asking price sits below the A$171? Wait—your ground truth puts the 25th percentile at A$171 and the median at A$284, so this lands just above the bargain threshold but still clearly on the cheap side of the pack. In plain terms: it’s a strong deal, not a premium ask.

These late-’80s Onkyos are usually attractive because they combine a proper quartz-synth tuner section with a solid integrated amplifier in one box, making them handy, space-efficient, and genuinely enjoyable if the unit is healthy. At this price, the upside is good unless the unit has scratchy controls, dead lamps, tuner drift, or relay/protection issues; with condition marked unknown, I’d want proof it powers up cleanly and all inputs work before moving fast.

Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.

About Onkyo

Onkyo traces its roots to postwar Japan, founded in 1946 in Osaka by Takeshi Goda, an engineer at Matsushita Electric who envisioned high-quality Japanese loudspeakers. Initially established as Osaka Denki Onkyo K.K., the company began production in 1948 with the acclaimed ED-100 speaker featuring a 25 cm driver, quickly building a reputation through LP concerts and innovative designs that resonated with audiophiles.

The brand excels in premium home audio, renowned for AV receivers, hi-fi amplifiers, and surround sound speakers that deliver exceptional clarity and power. Its portfolio spans turntables, DACs, headphones, and cables, bolstered by acquisitions like Pioneer's home electronics division in 2015, enabling cutting-edge integrations such as internet radio and high-resolution streaming.

Onkyo holds a solid mid-tier position in the hi-fi market, prized by discerning buyers for reliable performance and value rather than ultra-high-end exotica. Despite bankruptcy challenges in the late 2010s, its revival under new ownership preserves a legacy of technological innovation and pure sound enjoyment, appealing to both vintage enthusiasts and modern home cinema setups.
