I got the FLAC stations working on my Superuniti, Muso and Synology NAS.
First a big thank you to Adrian and Elmarko for their advice and input.
I thought I would write a summary guide that will help others.
Section 1 - Install MinimWatch, MinimServer, MinimStreamer
MinimWatch is installed on your laptop. MinimServer is installed on your NAS.
Once Minimwatch is working, green icon. (Java is needed), then goto Properties, Packages and Install MinimStreamer.
Section 2 - M3u file
This is very straightforward, but initially confused me the most. Use a text editor (Notepad++),copy and paste in the below text.
#EXTM3U
#EXTINF:-1,[RP;flac] Radio Paradise FLAC
http://stream.radioparadise.com/flac
#EXTINF:-1,[RPMellow;flac] Radio Paradise Mellow Mix FLAC
http://stream.radioparadise.com/mellow-flac
#EXTINF:-1,[JBRadio2;flac] JB Radio2
http://199.189.87.9:10999/flac
and then save as type (.txt) and with a filename e.g. (radio.m3u)
Install radio.m3u file in the same place as where you are storing your music.
A playlist icon appears on the naim app and you if you click there, your flac radio stations appear.
So both sections have to work properly but all the information needed is definitely contained within this huge thread so thanks to all the contributors.
Last note I am transcoding flac:wav and all work perfectly including all my hires and DSD albums.
Merry Xmas everyone!!!
