I know it isn't DIY, but after a few iterations of diy digital servers with RaspberryPis, I got fed up with the continual maintenance. My diy interests were decidedly elsewhere, so I took a punt and bought a Volumio Rivo purely as a destination for Tidal connect. I have been using it to feed an ifi microDSD for about 6 months now and LOVE the "just works" nature of it. Setup sounds great to me too. If anybody out there is looking for plug and play level Tidal connect streaming, I wholeheartedly recommend the Rivo. The guys that sell it out of Italy were responsive and generally great to deal with as well.
