The M-282 has a solid reputation as a straightforward, muscular two-channel power amp, and at US$150 this listing lands right around the market sweet spot. It sits just below the US$155 median and inside the usual US$143 to US$175 middle band, so this looks fair rather than aggressive.
What makes it appealing is the clean, high-value formula: dependable 100-watt-per-channel output, a simple layout, and enough current to drive a wide range of speakers without drama. If the unit is working properly and hasn’t been abused, this is the kind of used amp that can quietly outperform its price. The only real buying check is the usual one for older power amps: confirm clean channel balance, stable operation, and that all switching and trigger functions behave as they should.

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.
