Hi,
I have used Volumio for over a year now and just got myVolumio. I love the Tidal integration, I wish for real hi-res support from Tidal, but I realise that is a question for Tidal. I have ripped all my CDs to Flac on two SSD disks connected to a Pi 3B with a HifiBerry Digi+ and connected with toslink to a Hegel Röst. A very sweet sounding combo.
