Can the CXN100 support TIDAL’s Hi-RES FLAC streaming?

Yes, as long as you have the required TIDAL subscription, you will be able to stream TIDAL's Hi-Res FLAC files at their highest resolution on the CXN100 via TIDAL Connect.

TIDAL's StreamMagic app integration doesn't yet support Hi-Res FLAC playback, however this will be added in the near future.
