This is total balderdash! Roon sounds as good or better than any Squeezelite implementation to which I have listened, including iPeng.
Really Frank, what is your issue here. Fine, you don’t like Roon anymore. You think is sounds terrible and you don’t like the direction they have taken with the interface. I don’t see how Roon could do anything to make you happy. The Roon Core uses a robust TCP-based protocol to get the PCM data to the Roon Endpoints which pass that data on to DACs. Or the Roon Core sends PCM data to DAC directly. What else do you expect them to do? The PCM data can be bit perfect if no DSP functions or volume leveling is used. What does Sqeezelite do differently and better?
It seems you are complaining to just complain as you have no reasonable suggestions on how to improve the sound quality or the UI. Come with reasonable ideas or just go away!
