This US$450 asking price is ambitious, sitting well above the typical used market where the median is US$145 and the 75th percentile tops out at US$228. Even the highest external listing found for a serviced unit with shipping is only US$360, making this lone US$450 ask roughly double the 75th percentile of recent comparable USD listings.
The Onkyo M-5130 is a respected Japanese-made stereo power amplifier from 1989, delivering a solid 105 watts RMS per channel into 8 ohms with a robust, low-noise design that enthusiasts still value for its clean drive. However, at this price point, the listing demands verified condition: ensure the amp is fully tested, free of channel imbalance or thermal issues, and that the original power cord and RCA inputs are intact. Without proof of service or excellent original-owner condition, the premium over market norms is hard to justify.
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.
