I have been trying to research this, but have not had much luck in finding an answer. I have a Tidal Premiere account ($4/mo for 4 monhts) HI-FI On my PC the app lets me know if its Master or normal quality On my Roku, there is no indication on what the quality of the source is My Roku is hooked up to my AV8802A Pre/Pro It sounds great, and when I do my best to compare to Spotify it does sound more detailed, but I am sure there can possibly be bias on my end Does the roku pass lossless audio w/Tidal and how do you know?
