What customers say about "Key Specs"
Onkyo TX-NR757 7.2-Channel Network A/V Receiver
  • The best part is multi channel and phone app.
  • The sound definition per channel is very clear.
  • It allows for a lot of preset channels that's a plus. Reception is good--able to pickup many channels at a great distance.
  • 110 watts each channel give clear sound.
  • Very good sound quality with no distortion.
Onkyo TX-NR656 Network A/V Receiver
  • The sound is great, the bass channels are very deep, even compared to my old one. Love it.
  • In five years I couldn’t have my outdoor speakers on a separate channel all alone and now I can do that while playing different stuff inside!
  • Сhannel that takes everything through the receiver and surround sound so the TV volume doesn't have to be fooled with.
  • I have not been able to detect any distortion at all and I have turned this almost all the way up - There may be some at 100% volume, but if you have it that loud, things may break in your home from the crisp pounding Bass.
  • I can do without the intentional introduction of distortion. The auto setup was very good. I had to reduce the volume of my sub-woofer a tad.
  • I'm using this solely for two-channel audio (with my speakers connected only to the Front Left & Front Right channels). I don't have a monitor connected to it. The set up is cumbersome without a monitor.
  • The sound in the rear speakers was distorted and crackling and multiple times it would not detect some of the speakers.

What customers say about "Features"
Onkyo TX-NR757 7.2-Channel Network A/V Receiver
  • It connects to the radio via internet. It connects to the smart phone via Bluetooth. I repeat, it's not only a receiver, it's a smart computer to process sound.
  • It has adjustable 3 presets equalizer setting which works fantastic.
  • The graphic equalizer for each individual speaker set is great for dialing in some dead frequencies that seem to disappear in my room.
  • This unit works great with the speakers I bought & is a superb compliment to your smart tv, or blu-ray.
  • It is good but not perfect. It is a little awkward to use and the ios ap is marginal. I use the ap for multi zone music control because it is far easier that the remote but it tends to pause during play from time to time and has limited control over the unit and from time to time it hangs.
Onkyo TX-NR656 Network A/V Receiver
  • Using the built in AM,FM with just the inclosed antennas I was more than happy. Even though it is more than I hoped for, for use with the TV, I find myself watching less TV, and listening to more music. Highly recommend this AV receiver.
  • Its classy and responsive, quick to give you sound. I am happy with it and I think you would be to!
  • Bass response is good but not over done. Music seems very good with a good sound stage.
  • The included microphone "listens" to each speaker and determines where each one is and sets the crossover frequencies and measures the distance to each speaker for optimal listening automatically for you.
  • My biggest 'like' is the zone 2 pass thru. I connected this one to a Niles 6 speaker box to fuel my whole house with music.
  • There is the Zone 2 outputs which is what I'm using, and I guess they work fine for that, but that doesn't integrate in well with the normal functioning of the unit, so for example when I switch between inputs, I have to switch the zone 2 as well.

What customers say about "Connectivity"
Onkyo TX-NR757 7.2-Channel Network A/V Receiver
  • Have decent amount of HDMI output for all devices to connect.
  • This receiver is awesome, it connects to your wireless router, has tons of HDMI inputs, and sounds amazing through my Definitive Technology speakers. Setup was also a breeze.
  • Plenty of HDMI connections. Supports Apple AirPlay, huge for iPhone and Mac users.
  • Sound is wonderful and wireless and Bluetooth connectivity are simple to set up. Route cable through this amp and everything runs great!
  • I connected line for line and the output is not as good as the predecessor.
  • The instructions displayed on screen to connect everything through the receiver were a bit of a struggle but I made all the right choices the first time.
Onkyo TX-NR656 Network A/V Receiver
  • The Bluetooth connectivity works flawlessly as does the Airplay.
  • You can Bluetooth in with your phone and play music! Also, the wifi can link into your music library, and I mean it found everything to play. So, great item and we love all the options.
  • Using it's Bluetooth is as simple as can be. Playing my CD collection never sounded so good.
  • This system is easy to use, easy to set up, Bluetooth friendly and easy Wi-Fi setup. I updated the the software easily and now with Pandora, which already comes loaded but needs to be updated, I have an automatic screen saver in the big screen.
  • Lots of HDMI inputs and outputs in this, plus still some old RCA jacks for a turntable and CD player (yes, I still have and play both CDs and vinyl records)
  • I was a bit disappointed it didn't have pre-amp outputs, but like I said I couldn't really find a suitable switcher with those features that WASN'T a dedicated amp.
  • HDMI output issue problem . First unit could not find sources from DVD players or game systems. It showed its own video feed but would not find any others.
