Condition is unknown, so US$169 lands basically at the market’s center for this piece: just above the US$157 median and comfortably inside the typical US$134–US$172 spread. That reads as a fair asking price rather than a steal, with a little room only if the amp is exceptionally clean or recently serviced.
The M-5000 is sought after for its muscular, authoritative drive and the kind of clean, unforced sound that makes big speakers wake up. If the unit is original, quiet, and includes the right details a buyer wants to see—good cosmetic state, intact meters/lights, and proof of stable operation—it’s a solid buy at this level. At a fair price like this, the main check is not nitpicking, just making sure age-related service needs aren’t hiding underneath.
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.
