Onkyo 2012 Midline Receivers Preview


It is easy to get excited about the $1000 TX-NR717 until you see what the extra $200 for the TX-NR818 gets you. Audyssey XT32, 13.5 extra pounds and 25 extra watts per channel, and lots more.

Onkyo TX-NR818


Home cinema audio is often neglected, with TVs getting all the attention. The truth is though, that you could spend less on a TV and more on your audio system and have a more enjoyable experience. After all, most of the problem with TV and movies come...

Movie and TV soundtracks are brilliantly rendered, music sounds fantastic, some great online features, Android and iPhone apps,

Expensive, Onkyo just keep making better ones, menus can be slow and text input is a pain

Onkyo continues its yearly rampage of home AV. The 818 is brilliant, and the best-sounding AVR we've ever heard from the company. We're a little weary of saying this, but we honestly think this £1.000 model outperforms Onkyo's own £2.000 receiver from...

Onkyo TX-NR818


Onkyo's feature-packed AV amp is an absolute knockout

Extensive network features ; Potent movie sound ; Excellent picture processing ; Top-drawer build quality

No AirPlay support

Also on the back are eleven sturdy binding posts. These include terminals for the front, centre, surround and surround back channels, as well as front wide and front height channels for the built-in Dolby Pro Logic IIz, Audyssey DSX and DTS Neo:X...

Onkyo TX-NR818 Review


The Onkyo TX-NR818 is a powerful AV receiver, with some impressive options

Consumer review (

almost perfect


Still an exceptional product.... just wish that it could have internal circuitry to convert digital signals down to analog as well considering it is necessary for some external functions.

Upconvert, power, clarity, input sectability, etc

Main issue I have come across has to do with down conversion and outsourcing to tertiary receivers. No optical out, and zones 2 and 3 only output line OR powered if there is an analog audio connection on that input. You can sort of trick it by...

24fps bug is fixed, no more stuttering. Excellent receiver.


Just an upddate to the review I made before where I complained about image picture stuttering - Onkyo finally released a firmware update and fixed it. Apparently receiver was switching to a strange 24 fps mode instead of 23.976 (anytime you reffer to...
