It looks like that model supports Airplay, so you should be able to stream FLAC/ALAC via an apple device.  There's likely other ways with their DLNA support via transcoding software but it's a bit involved and not something I'm familiar with.

I've been using HEOS speakers for several years, and they've never made it too easy (the biggest advantage of Sonos IMO).

That said, I think you should be able to load TuneIn as Bill says.  The way I do that is not through the receiver, but through the app on a mobile device (phone, tablet).  I find that Apple devices work a lot better than Android.  On the app, you can add RP and the receiver should mirror the selections.  I have the app on several devices (I actually use an older iPad solely to manage HEOS).  It will pick up on using the speakers from apps (like Spotify) and automatically load the music for control (in the app)...but it's not so integrated with radio.  

You could also try the TuneIn desktop app.  I've never done it.

If your streamer uses TuneIn for managing station presets, then you won't be able to do FLAC. TuneIn should default to 320k AAC, which sounds quite good. 

Dear All,
