My Denon AVR-2312ci had a network radio but it was confusing and difficult to use so I just didn't use it. I had bought an Ethernet to Wifi adapter for the AVR-2312ci mainly for web browser control and firmware updates. I honestly can't remember if I ever did a firmware update but used the web browser control often since I had no TV On Screen Disiplay. Hard to navigate through layers of menus with a TV screen so web browser control was useful.
I'll likely skip the network apps and just use network radio stations which are pretty nice even though in MP3 format (that the kids think is HiDef

) .
I bought 3 Fire TV Stick 4K Max streamers. They were on sale for $35. But Fire TV sucks compared to Roku. Very glitchy needing reboots all the time. The reason was strictly for the Amazon Music Unlimited UHD content. While TVs only output 48Khz, they can still put out 16 or 24 bit resolution which is CD quality and higher. The sampling frequency creates a high end audio frequency already above my hearing at 48Khz so 96 or 192khz isn't much of a benefit but the bit depth is!
