This is a buyer’s market for this piece: at US$245, the asking price sits just above the US$212 median and below the US$249 75th percentile, so it reads as fair to slightly firm, not a bargain. It’s still close enough to the middle of the pack that I’d treat it as reasonable if the unit is clean and fully functional.
What makes it worth a look is the M-5010’s reputation as a straightforward, high-current power amp with solid build quality and the kind of reserved, controlled drive many Onkyo separates are known for. If the photos and seller notes suggest careful ownership, original condition, and no hidden issues, this is the sort of listing that can be a sensible pickup rather than a project.
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.
