You should be able to stream Tidal through HEOS in your Marantz. I have no direct experience with HEOS, but most reviews I've seen consider it inferior to the Wiim or Bluesound software. Try it, and if it works fine with your Tidal subscription, then leave it be. Note that Tidal also has Tidal Connect which allows you to use their app as a controller, which is usually preferred by many users over their streamer's software. I don't believe that HEOS supports Tidal Connect.
The advantage of the Wiim streamer over HEOS would be a better software suite and the ability to use Tidal Connect.
