People pointing out lots of expensive options but dipping in can be inexpensive and far superior to a Mac Mini.
You can test out a WiiM streamer. The Pro version allows an external 5v power supply. I’ve done that outputting to an RME ADI-2 via glass toslink (192K connection) with excellent results.
Have also used a ethernet connection to the WiiM. Running Blue Jean ethernet cables, the only cable difference I’ve heard with fiber in-between from the router.
Added two Cisco Meraki 8 port units and easily removed the internal power supply parts which are no longer needed. Ran one Blue Jean cable from the router via ethernet. Then another out with via fiber to another Cisco Meraki and then a short ethernet cable to the WiiM streamer.
Qobuz connect can be run from a tablet, phone or computer of your choice. No direct connection, right from the Qobuz server to the router and to your system. Very impressive output and should be tried.
Those who try this inexpensive options will be surprised at how little investment can make such an improvement. All less than the cost of a commercial "audio" network product.
