More info on mconnect.
Sorry for the long post but it’s a copy-and-paste from an answer I gave on another forum:
The maker of mconnect is Conversdigital. They have “player” apps and “controller” apps; you want the players not the controllers (which are for their own line of OEM network cards used in a number of streamers from small companies like PS Audio).
In the App Store look for “mconnect Player” (iPhone), and “mconnect Player HD” for the iPad. Here’s a link for the help page for the player apps, which is worthwhile since there are no instructions in the app for setting things up. http://www.conversdigital.com/eng/product/product04.php
Two months ago Conversdigital added sorting options in the favorites sections of Qobuz. For albums, click the three-dot menu and you can sort by Album, by Artist, and by Date Added. They also added “My Mix” playlists for TIDAL, if you use TIDAL; the only app to support that so far, except for the native TIDAL app.
So the API’s have been updated, and I was hoping BluSound and Lumin would have updated their apps to do everything mConnect Player does, but not yet. I think it’s only a matter of time, since mConnect shows it’s possible.
In the mean time, give it a try. I recommend the iPad app (mConnect Player HD) to start because it’s easier to learn the interface. It connects to any UPnP/DLNA streamer. I started using it back in 2018 to stream to an Oppo 205. When I got the Lumin I was pleasantly surprised that the app worked with it too.
Note: mconnect Player HD, the iPad version, only works in landscape mode. So, if you don’t like holding your iPad in landscape position then go with the non-HD version (it works on both iPhones and iPads in portrait only).
