KEF LS50 Wireless + Mac Mini + ? + Radio Paradise FLAC = heaven

Having having recently acquired the great sounding KEFs, I would like to listen to Radio Paradise FLAC streams.

I am looking for an alternative to streaming thru the browser to maximise SQ. I have tried tried the likes of Audirvana and Amarra for streaming Tidal but neither seems to offer internet radio streaming. 
Are there any alternative apps out there that you can recommend?
