Fair asking price, right on the money for the recent used market. With a median comparable at US$146 and a 25th–75th percentile band of US$122–US$162, this listing sits exactly at the center of the pack, so it reads as fair rather than cheap or ambitious.
That makes it a sensible buy if the unit is clean and unmodified. The M-5000 has a solid reputation as a serious stereo power amp: plenty of current, good control, and the kind of authoritative, no-drama presentation that suits real speakers well. At US$146, the upside is in condition, originality, and whether it’s been serviced; if it powers up quietly and looks cared for, it’s the sort of vintage amp that can be a very satisfying pickup.
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.
