Onkyo’s TX-NR646 sits in that sweet spot of midrange AVR usefulness: enough HDMI switching, decoding and power to anchor a proper living-room system without the cost or complexity of newer flagships. At A$325, this is basically fair against your local comps — just above the A$324 median and inside the A$284–A$365 interquartile range, so it’s not a steal, but it is squarely in-market.
The upside here is the usual Onkyo value play: solid feature count for movies, TV and gaming, plus a known, straightforward platform if you want a competent surround hub rather than a boutique sound-chaser. In very good condition, it reads as a sensible buy if it’s fully functional, includes the remote and calibration mic, and hasn’t been stressed by heat or years of hard use.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
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.
