I haven't heard of any.
Tidal is the premier stream service for quality. You can get a 3 month free subscription by downloading the Sennhieser Captune app, sign up for Tidal, then go to Tidal directly with your new sign in ID.
You should be able to find something you like.
Otherwise there are many thousands of radio streams, but usually at 192kb/s, the occasional one does 320.
I have been enjoying it with the chromecast for a few weeks now. It does drop the connection frequently, but that maybe due to my ancient iPad or perhaps the Tidal app, or network overload, most likely it's the iPad.
