Onkyo TX-8140

This receiver was a poor match for my B&W speakers, producing harsh midrange and highs compared to the Yamaha it was supposed to replace. This Onkyo did deliver very punchy sound. If you want your ears to be punched, or you have speakers with weak treble response, this may be the receiver for you. I kept getting listening fatigue after a few minutes, had to return it.

Is what it is

Want a good stereo receiver with good sound and some nice features, then you have it. The radio/receiver function I like as you can manually tune it (I don't like when a device tells me it's smarter than I am and won't tune in a signal I like but it doesn't :)). Lots of inputs for a variety of devices, and importantly to me, Line-out for feed to my downstream systems. That it's on my home network for remote control and Internet music is great, as is bluetooth. Drives my Bose and other speakers just fine.

Great Amp

Just recieved this the other day, and I've used it to play vinyl, cds and bluetooth connected devices. The setup was straightforward, syncing is simple, and the sound is solid. I'm very happy with my purchase. The only thing that had me initially struggle was the front interface to change inputs, but after a few minutes of reading the manual, it's no longer a problem.

Onkyo TX-8140

Purchased online and free delivery to my door. Great packing and no damage. Replaced my old 7.2 channel Sony Receiver with the new Onkyo in a couple of hours. Easy to operate with knob bass and treble controls. Bluetooth from my iPhone 6 controls all my music from up to 20' from outside. Very satisfied with sound quality and max volume distortion. Great 2 channel stereo.

Onkyo Stereo Receiver TX-8140

Apart from a minor irritation with some of the screen layouts and dealing with a very large remote control, this is an excellent stereo receiver. I primarily purchased this for playing my Sacred and Classical Music CD collection and I have not been disappointed. The output is more than adequate; clarity is excellent and I do not have to crank up the volume control in order to enjoy the music.
