As far as audio quality, only Tidal and Qobuz offers lossless CD quality or higher resolution which is definitely better than FM.
Streaming from Rhapsody and Spotify is compressed and equivalent to FM Stations.

Thanks, your answers go directly to the point.  Take care, Jim

Another source for high resolution streaming audio is Amazon Music HD. I’ve been testing it and am quite impressed. If you’re already an Amazon Prime member the additional cost is very reasonable. But what may be most important in deciding on a streaming service is which of the catalogs most nearly matches your musical preferences. Trial memberships are the way to explore that. The Ultra HD tracks on Amazon Music HD often sound better than the same CD in my system.

I feel a good server slash streamer is essential to streaming quality.

Bluesound Node can be a starter device.
