@lubachl The local NPR station in New Orleans, WWNO has 3 streaming channels they offer: News, Classical, and Jazz. Meanwhile, the local WWOZ station is strictly music - local, jazz, funk, etc. Both stations broadcast in HD (although it’s dependent upon signal strength and radio HD isn’t like streaming HD) which is fine for the car. But at home, I stream them because the SQ is better (still not high-res) than the tuner/radio channel. I’d say that for home listening, stick with streaming your radio station’s channel. To access the WWNO Classical channel on your phone, you can use the TuneIn Radio App and search for WWNO.

If you use the TuneIn radio app on your phone, you can also search by music type and filter all of the classical radio stations available to stream.
