So, I finally got to pick up the AVR-X3600H yesterday that was on order, and I spent the day setting it up. Still doing a bit of tweaking, but i'm happy to say the two main features I wanted, are in fact working great. There is a slight issue with setting volume by voice though. Not a deal breaker however. It works great setting the volume , but if you make adjustments using the remote as well, it doesn't sync up eg. If you are at volume 0 as an example and say "OK Google, Volume 30 on the Denon", it changes the volume to 30. If I continue to speak volumes it works great. As soon as I use a remote control to modify the volume, and then use voice to change the volume, the volume will be out by the amount you changed it using the remote. Eg. If it was set by voice to 30 and is at 30, and then I use the remote to change it to 33, and then use voice to set it to 50, it will actually change it to 53 instead of 50. I can't see any way of fixing that so maybe it's a bug and may be fixed in a future firmware update.
Here's some things I love about the receiver and how it compares to my Sony STR-DN1080.
* If I watched a Youtube video on the TV, I had to use an optical cable to get sound back to the Sony receiver for some reason. This isn't the case with the AVR-X3600H. It just works without the need of an optical cable. Both receivers I believe had E-ARC so no idea why I had the issue with the Sony.
* Every single setting, including distances, Levels, graphic equalizer etc. all can be modified using a web browser on the same network. The Sony doesn't have that feature, and I love it on this receiver. It makes it so easy to make changes to tweak things and it updates the receiver in real time so you can get immediate results.
* There's a configuration backup and restore option on the AVR-X3600H which saves the configuration to a USB stick. This comes in really handy so you can make backups when you tweak settings, and then restore when you bugger something up. This isn't a feature of the Sony receiver. I've already used the feature, and it works great.
* I can be listening to Spotify, or any other audio source ie. USB, network, etc, while watching cable TV (using a Set Top Box), or Apple TV, or PS4 etc. I've tested it and it works great. This was one of the major features I wanted and it's not available on the Sony receiver.
* I love the amount of tweaking I can do., and the audio is the same if not better than the Sony receiver albeit, i'm still getting used to the slight change after changing receivers. So far, i'm really happy with the receiver though.
I feel like there are only a couple of minor annoyances that stop it from being really awesome, but the annoyances are very minor, and can be resolved in future firmware updates potentially.
The first is the volume issue above, and the second is the fact the Denon doesn't show up in Google Home as a device that you can add to a group. The Sony receiver could do this so you could add all the Google Homes around the house into a group which included the receiver. The device that comes up the Google Home app for Denon is the HEOS name and while you can control it by voice, you can't add it to a group and play it along side all the Google Homes.
Apart from that, it's a great receiver, and I definitely feel like it was a worthy upgrade. I'll be in heaven if Denon ever fix the above issues. I can't find any way of sending them feedback though.
