The US$1,649 asking price sits just above the median of US$1,500 for recent used listings, making it a fair but slightly ambitious deal rather than a bargain, especially since it exceeds the 75th percentile of US$1,575. With the condition listed as unknown, this small premium is justified only if the unit is in pristine, original-owner shape; any signs of wear or untested operation would push this into overpriced territory.
The M-5000R remains a respected Class A/B stereo power amp from Onkyo’s Reference series, delivering clean 80W into 8Ω (150W into 4Ω) with exceptional damping factor and low distortion. Its symmetrical layout, bridgeable design, and DIDRIC distortion-reduction circuitry offer meaningful upside for serious analog or digital setups, and if this listing includes the original remote, power cord, and box, it becomes a compelling buy at a fair price for a well-built, rare find.
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.
