The Onkyo TX-SR805 is a legendary 7.1-channel home theater receiver released in 2007. It delivers 130 watts per channel, features THX Ultra2 certification, and supports advanced lossless audio codecs like Dolby TrueHD and DTS-HD Master Audio.
Key Specifications & Features
• Power Output: 130W per channel into 8 ohms (20Hz–20kHz, 0.05% THD)
• Surround Processing: THX Ultra2, Dolby TrueHD, DTS-HD Master Audio, Dolby Digital Plus, and DTS Neural Surround
• Video & HDMI: 3 HDMI 1.3a inputs, 1 HDMI output (supports 1080p pass-through and analog-to-HDMI video upconversion via Faroudja DCDi Edge)
• Room Correction: Audyssey MultiEQ XT automated speaker calibration
This is an ambitious ask at US$280. Against the recent comparable pool, that sits well above the US$175 median and even above the US$358 75th percentile only if this exact unit has unusual provenance or restoration; otherwise it’s not a bargain.
What keeps it interesting is the TX-SR805’s reputation as a substantial, older flagship-style receiver with serious power delivery and full 7.1-channel home-theater muscle. The included power cable is nice, but at this price the buyer should want proof of clean operation, no HDMI or relay issues, and no heat-related trouble; if it’s fully serviced and truly mint, it can still be a solid pickup for someone who wants vintage Onkyo heft.
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.
