These two devices are designed by world-known manufacturers who are ready to provide us with first-class solutions. Both models are great, but there are still some differences between them and you need to pay attention to some the details to find the device that suits your needs perfectly. I have cheeked official websites, forums and user reviews to gather all information that will help you choose between these two models.
The receiver is easy to set up. The included calibration microphone works great and is able to automatically set the sound levels of the speakers. The picture and sound through the receiver are great. The manual is decent. Built-in support for Google Cast (aka Chromecast). Audio only though, no video.
They should move one of the HDMI inputs to the front. All of them are in the back, so if you want to add a temporary device, you either have leave an empty HDMI cable hanging off the receiver or mess with the back of the receiver It doesn't support Pandora even though it says it does.
Plenty of HDMI ports, 2 monitor HDMI out, one being the all-important ARC, lots of speaker setup options and plenty of power pushed.
This item has 7.2 channel full 4K Ultra HD AV receiver with 185W per channel, built-in HEOS wireless technology, Bluetooth, Dolby Atoms, Dolby vision compatible, HDR, HDMI 8 in/ 2 out.
It is a great model with many useful features. It is easy to use and it looks modern, but it is not as powerful as the model from Sony.
The device is great in terms of compatibility with different devices and availability of playing different files, but the main disadvantage of this model is its total power output. Some people may find 185 Watt insufficient.
I would say that it is not that easy to choose. The main advantages is Denon built-in decoders that are able to play almost any kind of files. However, this device is not that powerful (185 Watt) and its operational power consumption is 460 Watt vs Sony 240 Watt. The main advantage of the model from Sony is the total power output, while the main disadvantage is poor built-in decoders, which may result in issues when you try to play certain files.
If you need a powerful device, and you are sure that you will not need those decoders, then Sony is the right one for you. If you do not need that amount of power and you need good compatibility then consider buying Denon AVRS930H.
