For myself there are 3 aspects - Audio to a device, Display to a screen, and Control from a device. Plus, it has to work for the whole family.
In my example I want the control and display to be via the huge 4K TV dominating the room where everybody consumes their media. The sound goes to the cinema surround amp and speakers clustered around the TV. That’s where everybody’s eyes and ears are.
Nvidia seems like a perfect choice for control - as it is already used by the family with just a remote control to consume media. Currently, you need yet another another device for ROON control (laptop, phone, tablet) and that isn’t push-remote-button-as-normal-and-play family friendly.
Consequently, Plex always wins over ROON as first choice music player (also does music video on the 4K screen).
