The Onkyo M-5160 is a respected vintage stereo power amplifier known for clean 150W/ch output and ultra-low distortion, making it a solid choice for serious 8Ω speakers. At US$280, this asking price is ambitious compared to the typical used market, sitting well above the median of US$250 and the 75th percentile of US$257 from your own database of four recent listings. It’s not a bargain, but it’s not wildly inflated—just a bit above fair value for a standard used unit.
What makes this a worthwhile consideration is the M-5160’s reputation for stability and musicality, backed by specs like 0.09% THD and a 5Hz–100kHz frequency response that hold up well today. If this listing is from an original owner with clean condition and possibly includes the manual or original box, that added care could justify the slight premium. Without those extras or signs of wear, however, a buyer might reasonably wait for a listing closer to US$250.
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.
