What customers say about "Key Specs"
Denon AVR-X2300W 7.2 Channel Full 4K Ultra HD AV Receiver with Bluetooth
  • At 95 watts/ch you will have plenty of power to drive all but the most inefficient speakers. If you have high efficiency speakers like Klipsch or others 95 watts can actually be painfully loud.
  • My son has this unit and a Klipsch 7.1 setup in his room and he has never turned it up past -11db, which is roughly 6 watts/ch and that was VERY loud. I have yet to ever hear distortion from any of my Denon AVRs.
  • If your subwoofer has it's own power amp (as mine does) then this 95 watt receiver is fine for small to medium size rooms at a high volume level. This 2016 Denon model has pretty much anything you could want in an AVR.
  • I like the pure sound and power the unit delivers. The 4K resolution is unbelievable
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"
Denon AVR-X2300W 7.2 Channel Full 4K Ultra HD AV Receiver with Bluetooth
  • As far as features of the AVR-X2300W, it has all the other latest features and technology you could possibly want, including: Full 4K Ultra support up to 60hz and 4K Ultra up-conversion @ 30hz, HDMI Pass-Through, built-in Wi-Fi and Bluetooth, Dolby Atmos, TrueHD, DTS:X, HDCP2.2, HDR, and more.
  • This AVR also has Dolby Surround, DTS NeuralX, and Multi-Channel-Stereo. These will all take a stereo 2-channel source and smartly incorporate all the speakers in your setup.
  • My current tv is 1080p resolution and this receiver will handle the new 4K video when I upgrade.
  • The Audessy room calibration worked well for me
  • A new feature is the internet connectivity. I've used the Internet radio feature and it works well.
  • Only one thing that I wish it had (like my old AVR) is a switched 120 volt connection to run my cabinet cooling fan.
  • After initial setup, navigating the setup menu requires someone with patience - and time. Don't try to configure surround options (for example) while the family is waiting to be entertained.
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"
Denon AVR-X2300W 7.2 Channel Full 4K Ultra HD AV Receiver with Bluetooth
  • Connections are clearly marked and setup is a breeze.
  • Setup was a breeze compared to what I was used to when I last set up a receiver 12 years ago
  • On screen menu and Audyssey was amazing. I had everything setup and calibrated within 20 minutes for a simple 5.1 setup with a TV, Xbox, AppleTv, Switch, and PS4 to the ARC port on the TV
  • Renamed all the inputs for what they controlled which made it much easier to keep straight what was what
  • Wouldn't connect to Wireless N 5G (May be the distance from access point) but works fine on 2.4, HDMI control for Roku Ultra is a bit sketchy-Won't turn receiver on or switch to correct input on receiver and often get HDCP error message.
  • The only problem I've had is that they REALLY bury this information: All those analog connections in the back do not convert to a digital signal and output to the HDMI. LOL ANNOYING
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.
