The TX-8140 delivers stereo power at 80W/Ch (8 Ohms, 20 Hz to 20 kHz, 0.1%, 2 Channels Driven, FTC) or 110W/Ch (6 Ohms, 1 kHz, 0.1%, 1 Channel Driven, FTC).

Or pair up and enjoy whatever's playing on your Bluetooth-compatible device for cinematic sound. It also comes loaded with Spotify, Pandora, SiriusXM Internet Radio, Slacker, and TuneIn. You can select a station and search for music available on these services via the Onkyo Remote app on your phone.
Low-Distortion Sound from Any Format
An Asahi Kasei AK4452 digital-to-analog converter unlocks the potential of any audio format with its low-distortion, sound-enhancing filtering technologies.
Quick Access Presets
Get instant access to four of your favorite FM/AM or Internet radio stations at the touch of a button. Four preset buttons on the faceplate go straight to the stations. You can even wake up the receiver from standby mode by pressing one of these buttons for instant radio.
Hi-Res Clarity & Detail

    Onkyo TX-8140 reviews

    TX-8140 2.1-Channel Network Stereo Receiver is rated 4.6 out of 5 by 5.
    Rated 3 out of 5 by from Lacking mid-range I noticed a lack of mid-range & tested on 2 sets of speakers-- full size Polks & Sony bookshelf. �Also, the printing for control inputs/knobs on the front is very small & difficult to see.
    Date published: 2018-02-12
    Rated 5 out of 5 by from Great Amp, Tuner I love the new device in all ways but I still do not know how to connect it to my WiFi.
    Date published: 2017-04-28
    Rated 5 out of 5 by from Fantastic Stereo Receiver I bought this stereo in order to play music from my smart phone as well as music from my cable network's music channels. The sound is sharp and clear and \\the unit easily powers my fairly large and expensive speakers. The output from my TV goes into the input on this device and the music channels never sounded so good. I will eventually use the wifi capability to play music from my pc. I would highly recommend this receiver.
    Date published: 2018-09-24
    Rated 5 out of 5 by from Nice little unit Great little receiver, bluetooth works flawlessly and decent sound compared to some cheapie Kenwoods I was using.� A little tough navigating the USB flash drive menu to get individual songs played, but there is a learning curve
    Date published: 2018-06-06
    Rated 5 out of 5 by from Great unit Great features and nice sound. I use the Onkyo remote app to control the unit which is much easier than using the remote control. I have my TV connected as well as a C D player but mostly use it for music.
