What customers say about "Key Specs"
Onkyo TX-NR575 7.2 Channel Network A/V Receiver
  • I really like the sound quality and the bass really!! Seems to have improved with this receiver!
  • The sound is fantastic and has plenty of power for my 5.0 speaker setup, 4 Klipsch KG1.2 with a Klipsch KV2 Center speaker which is voice matched to the KG1.2s.
  • The DAC in this receiver is really great, I listen to my music with all channel stereo now.
  • Using all 7channels and whether using bluetooth or even very clear radio channels all is crystal clear even pushing it towards top. Picks up all correct surrounded speakers.
  • I cannot get the 5.1 setting on the device to play the center channel and the front channel together at the same time.
Onkyo TX-NR686 7.2 Channel THX Certified Network A/V Receiver Black
  • This is my third Onkyo receiver in a row since Sept 2008 and its also the cheapest and best sounding to boot!
  • Loving this receiver! It’s running my set of Polk Audio speakers (5.1, and the front mains are bi-amped).
  • The sound is balanced and FULL. Lots of AVRs can be loud, but the sound is kinda bland and lifeless. This AVR has a wonderful, warm sound, at all volume levels.
  • Onkyo is the best for me, they are low in cost, good sound and all the basic features just like the higher price systems.
  • This receiver gets heavy use between movie watching, audio playing and gaming. Working well.

What customers say about "Features"
Onkyo TX-NR575 7.2 Channel Network A/V Receiver
  • Setup was quick, it first sets up with a wizard when you first turn it on so make sure you have your tv on so you can view the messages.
  • I love the zone 2 feature which is great to send audio to the game room with one system.
  • You can control the volume power and settings etc. with the app, great for when you in zone 2 and not in reach of the receiver in zone 1.
  • I was a little worried that the 575 would not find the FLACs because of all the blah blah blah about Windows Media Player but it seems it will work with any DLNA server.
  • Its loaded with features, too many to list, and it sounds great. . I love that all my devices get channeled through it and it has a decent auto calibration.
Onkyo TX-NR686 7.2 Channel THX Certified Network A/V Receiver Black
  • Updating the software allows your SONOS Connect to power on and switch inputs on the Onkyo. I have installed dozen of Onkyo receivers and they are rock solid. Never had one go bad yet.
  • Easy to set up, loads of capabilities, sounds great, etc. All in all, I'm very happy with it.
  • The app you can use is great, bluetooth, e.t.c, all very convenient.
  • Bought this because my old onkyo malfunctioned. So worth the upgrade with Bluetooth. The quality of the user interface feels a lot better.
  • Wow! Great feature and sounds fantastic. Overall I am very happy with the unit and love that I can control the audio from my android and iphones.

What customers say about "Connectivity"
Onkyo TX-NR575 7.2 Channel Network A/V Receiver
  • The setup and settings are done through the HDMI to our projector or TV is some people case, and its very easy to navigate.
  • I really enjoy having so many HDMI inputs with audio pass through. My old system only had two HDMI's this has 6.
  • I like the fact that’s I have all these HDMI channels to play with and the beautiful setup feature.
  • Oh yeah! Bluetooth and iPhone links work great with display on TV. Sound quality is superb.
  • What I really HATE!! About this receiver is!!! The Bluetooth! It never works!!!
Onkyo TX-NR686 7.2 Channel THX Certified Network A/V Receiver Black
  • This new Onkyo has plenty of input and output HDMI connectors in addition to all the old style video/audio inputs.
  • Very clear and sounds great, the turntable sounds awesome also. Blue tooth, network. What a cool combination.
  • Onkyo has better tech, better sound, better Bluetooth, better everything. Customer for life.
  • ARC function through HDMI? Yes, it has it. But you will have to mess with the settings constantly when it randomly quits working.
  • Bluetooth pairing (no sound) issue! Seems to be a common problem. Sometimes it plays audio from a connected Bluetooth device, but sometimes it does not.
