I tried to find and play internet radio with CD quality on Sonos, but I failed except Radio Paradise. (I tried to add Naim Radio FLAC stream on Tunein and got failure in playing it. )

Is there any radio station of CD or Hi-res audio quality, which can be played on Sonos except Radio Paradise?

I don't want to find music and play them. I prefer radio.

I prefer music without lyrics like classical music. I think Jazz etc. are fine.

If there's no free service, is there a paid service?

---- Does Roon music player do this job?

---- Sonos Radio isn’t available in my country, but I have questions. Are Sonos Radio HD stations just playlists or on-air? If they are playlists, then do they update their stations frequently?

Thanks in advance!
