Not sure about Tidal "Connect" (apparently a work in progress like the WiiM Home app on PCs), but Spotify Connect will work well from your desktop machine thru/to the WiiM. I use the Windows WiiM Home app all the time because I stream local files and only want to deal with one piece of hardware through my day, but, as harkpabst noted, it's a beta version and the priority to bring it up to snuff with the versions on other platforms is, well, rather low....
