Against recent USD comparables, US$1,400 lands well below the US$1,500 25th percentile and far under the US$2,100 median, so this reads as a strong buy rather than merely fair. It is the kind of asking price that should get an Onkyo fan’s attention quickly.
The M-508 is valued for big-current muscle, solid dynamics, and that classic late-80s high-power separates feel; when healthy, it can make demanding speakers wake up without sounding strained. At this price, the main question is condition and service history rather than value: a clean, original unit with no scratchy controls, relay issues, or prior abuse is a very appealing opportunity.
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.
