May be I am slow, Radio Paradise has launched a FLAC service accessible from their iPhone and Android Apps, and Michael Herger has created a plug-in for LMS. Radio Paradise say they will provide access via their new web player in Feb 2018 and a FLAC stream sometime after that.
I have successfully used it on my RPI3/PiCorePlayer running LMS & a Squeezebox Radio both synchronised and controlled from the Squeeze Control app on my Android phone. The sound is really a step-up from the 320K stream. Its really worth trying out if you have not done so already.
