Thanks, Matt. I really appreciate you sharing your experience and advice.
Does MediaMonkey on your iPad do anything with the NAS-stored content, or does it only airplay the content stored on the iPad?
I was looking at Kodi, although I might be more inclined to KodiBuntu for a variety of reasons. Do you enjoy the UI?
Do you like FooBar2000?
The beauty of this option is that it is possible to stream the music to a different zone at the same time as watching something from Kodi.
I need more info on this. What receiver are you using? I ask because one stumbling block I've run into is that most receivers seem to only have one DAC path; in order to get content in Zone2, I have to supply an analog signal to my Onkyo 805. I know I've wallowed around in this question at other points, and I apologize if you've already advised me.
Thank you again for your help.
