This is ambitious at US$199. Recent used comps for this model cluster much lower: roughly US$48 plus shipping on eBay, US$149 on another eBay listing, and about €116–€170 on marketplace and HiFiShark-style comps, which puts a fair US-dollar used range closer to roughly US$50–US$150 depending on condition and region.
What makes it worth considering is that the TX-SR304 is a straightforward, no-frills 5.1 Onkyo receiver that can be a solid budget home-theater hub if it’s fully working and the accessory bundle is complete. The included cables and accessories add some convenience, but they do not move this into bargain territory at this ask; I’d only bite here if the unit is exceptionally clean, tested, and comes with the original remote and anything else that’s genuinely hard to replace.
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.
