If Tambaqui dac does not support DLNA:
Some people report using WiiM products, like the WiiM mini or WiiM Pro, with MC over a network. MC targets it as a DLNA renderer, then you connect one of the WiiM's digital outputs to the Tambaqui dac.
Here's one example from user @dtc:
https://yabb.jriver.com/interact/index.php/topic,136948.msg949527.html#msg949527Darko (
https://darko.audio/ (search on "WiiM")) has several reviews of WiiM streamers. You can probably find other network streamers with DLNA capability that will also work, likely at higher price points, but still much lower cost than the Tambaqui.
Streamers with Chromecast built-in can also be made to work if you run BubbbleUPnP on your MC server to make the Chromecast look like DLNA to MC. Chromecast may have issues with gapless playback, so if that matters then you are probably better off with direct DLNA.
You might also ask Mola Mola what they suggest.
