Onkyo TX-NR676 7.2 AV Receiver 100WPC Atmos Bluetooth
7.2-channel network home theater receiver with Dolby Atmos, DTS:X, Bluetooth, Wi-Fi, 4K/HDR HDMI, and built-in phono stage, in very good condition with original remote.
The Onkyo TX-NR676 is a versatile 7.2-channel AV receiver designed as a full-featured hub for modern home theater and music. It delivers up to 100 watts per channel into 8 ohms (2 channels driven) and supports up to a 5.2.2 Dolby Atmos or DTS:X layout for immersive surround sound. Built-in Wi-Fi, Bluetooth, Chromecast built-in, DTS Play-Fi, AirPlay, Spotify Connect, and TuneIn make it easy to stream from phones, tablets, networked music libraries, and online services without extra boxes. Very good cosmetics and the original remote make this unit an attractive upgrade for systems needing HDMI 2.0, Atmos, and robust streaming in one chassis.
Seven HDMI inputs (including one front) and two HDMI outputs provide generous connectivity for modern sources, with full support for 4K/60, HDR10, Dolby Vision, BT.2020, 3D video, and HDCP 2.2. Legacy gear is supported via component and composite video, plus optical and coaxial digital audio inputs and multiple analog stereo inputs. A key advantage for vinyl listeners is the dedicated phono (MM) input with ground terminal, allowing direct connection of a turntable without a separate phono preamp. Onkyo’s AccuEQ with AccuReflex room correction is available if you choose to use it, but will not be mentioned as including a calibration microphone unless specified with the unit.

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.
