Cool, so you kinda’ know what you want it to do. Have you tried Audirvana Studio? You can try it out for free and they’ll give you 30 days. The iOS app has come a long way since I used it last. Played with it and Roon this weekend.
Audirvana and Roon are fun but I’ll stick with the iTunes Remote app in my iOS devices for the albums stored in my Mac mini and WD HD that is used in iTunes server mode when the trials are done. I can use the Onkyo DTS Play-Fi app in my iOS devices and Mac mini M1 for the Qobuz and Tidal services.
Audirvana works over the network without any extra hardware needed for one reason or another and will send 24/192 tracks to receivers that can handle them. For my setup, it works using the Music Server app in the NET source input of my receiver and I use the iOS app as the remote control if I’m not sitting in front of the TV using the Mac mini to go online. Then, I just use the Mac’s interface.
With Audirvāna, enjoy all your streaming and local music with the best playback sound quality from a computer.
