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.

Which Onkyo is which?

TX stereo receivers: a long run from the 1970s to today, such as the TX-830 of the late 1980s and the TX-8030 of 2011.

TX-SV and TX-DS home theatre receivers (1990s to about 2001): for example the TX-SV 454 and the TX-DS484.

TX-SR receivers (from 2002): such as the TX-SR502 (about 2004 to 2005) and the TX-SR706 (about 2008 to 2009).

TX-NR network receivers (2010s): with network and streaming features, such as the TX-NR626 (about 2013 to 2014).

TX-RZ receivers (from 2016): the newer flagships.

DX-C CD changers: from the DX-C210 of 1993 onward.
