Onkyo TX-8522 Stereo Receiver – Thoroughly Tested & Working Perfectly, with Onkyo Remote

Experience powerful, pristine stereo sound with the Onkyo TX-8522—a premium 2-channel receiver combining high-current amplification, sophisticated engineering, and modern connectivity. This unit has been thoroughly tested, works perfectly, and includes an Onkyo remote for convenient operation from your listening chair.

The TX-8522 delivers a robust 100 watts per channel into 8 ohms using Onkyo’s acclaimed Wide Range Amplifier Technology (WRAT) and high-current, low-impedance design. The discrete output stage circuitry, oversized isolated power transformer, and heavy-duty extruded aluminum heat sink ensure clean power delivery and long-term reliability. This receiver easily drives speakers down to 4-ohm impedance, making it compatible with a wide range of bookshelf and floorstanding speakers.

Beyond its exceptional amplifier section, the TX-8522 offers comprehensive connectivity including a high-quality moving magnet phono input for turntables, three audio inputs, two A/V inputs with composite video switching, and dual tape outputs. The built-in FM/AM tuner features 40 presets with station naming and direct access tuning. Additional features include XM Satellite Radio ready capability, iPod dock compatibility (with optional Onkyo dock), Pure Audio/Direct mode for bypassing tone controls, and A/B speaker switching for dual speaker pairs.

Onkyo was founded in Osaka in 1946 by Takeshi Godai as Osaka Denki Onkyo, and the name was shortened to Onkyo in 1971. We carry Onkyo AV receivers and stereo receivers, cassette decks and CD players. We've had more than 60 Onkyo listings so far, covering more than 50 different models. Every AV receiver we list is tested input by input on our bench: each HDMI input and output, the analog, optical and coaxial inputs, the subwoofer outputs and the wireless features where it has them. Every used Onkyo here is inspected, tested and serviced as required, then photographed in-house and covered by our Bumper-to-Bumper Warranty and Perpetual Trade-Back Program. Don't see the model you want? Tell us on First Dibs and we'll email you when one arrives.

The Onkyo models we've sold most often include the TX-SR313, TX-NR626 and TX-SR706 AV receivers.

The Onkyo story, 1946 to today

Takeshi Godai, who Onkyo says had headed Matsushita Electric's speaker factory, founded Osaka Denki Onkyo in Osaka in 1946. Stereophile translates the name as "Osaka Electric Sound Harmony", and the company shortened it to Onkyo in 1971.

Integra and home theatre. Onkyo's Integra amplifier line began in 1969, and by the 1990s, Stereophile says, Onkyo had become a well-regarded home theatre brand.

Pioneer joins. In March 2015 Onkyo took over Pioneer's home AV business, and both brands carried on under their own names.

New owners. In September 2021 the Onkyo and Integra brands passed to a joint venture of VOXX's Premium Audio Company and Sharp, which builds the products. The old Onkyo company in Japan filed for bankruptcy in May 2022, after the brands had been sold. Gentex bought VOXX in April 2025, and Onkyo says its research and development is still in Osaka.
