This A$160 asking price is a strong bargain, sitting just below the 25th percentile of A$162 for the Onkyo TX-SR578 in the Australian used market, where the median is A$263 across 347 comparable listings. You are effectively paying less than the lowest quarter of recent asks for a tested, working unit, making this an excellent entry point for a 7.1 receiver at a fraction of its original ~A$850 launch cost.
The TX-SR578 remains well-regarded for its robust 7×130W power, 1080p HDMI upscaling via Faroudja DCDi, and support for lossless Dolby TrueHD and DTS-HD Master Audio. With HDMI 1.4a handling 3D video and a dedicated front Universal Port for peripherals, it offers meaningful performance for home theater builds without modern gimmicks. Since the listing confirms it’s tested and working, this clean deal represents a genuine buying opportunity for enthusiasts seeking reliable, high-power analog surround at a rare price.

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.
