Using Volumio on various (Raspberry Pi + Justboom amp hat or dac hat) systems to use and share music, in mostly .flac format, from my nas drives. The flexibility and ease of use is first class. Whether engaging through PC or Android the output quality is easily a match for my home hi-fi systems. (Naim pre and power, Arcam Cd, or Marantz CD Audolab Amp) Amazing range of plugins and options. Writing this while listening to Paradise Radio melo mix at 1.30 am via Raspberry Pi 3 - amp hat and Morduant Short M10 speakers. Fleetwood Max - Albatross. Going to bed happy and chilled... Nope Lyle Lovett just came on.. I'll stay awhile...ah now Jerry Garcia...
