Digital Sputter or Stutter?

I recently got into streaming, buying the NAD CS1 and hooking it up to my desktop sound system (Rotel RA-870 integrated/Parasound Zdac/ NHT Super Zeros) via the LAN connection.I subscribe to Tidal and was just learning some streaming basics when out of nowhere, what I would call digital sputtering/stuttering is being produced for some reason at the end of a music track. The one thing I noticed that seemed to be concurrent with this blasted noise was that the streaming quality indicator reads 'LOW' when using the CS1, but 'HIGH' when streaming on my phone. I suspect this has something to do with the LAN connection, but maybe it could be some other gremlin?
