Hi was thinking to use on a Rpi 3 / HIFIBerry Digi + pro (with a nice Linear power supply)
feeding into my (posh) USB/SPDIF converter and on to my (posh) DAC

I want to play music from my NAS drive (synology) and TIDAL High Res Streaming...

Which controller would anyone suggest?

I've looked at Roon Audio, looks nice but not sure with the RPi (and subscription is heavy)

Then looked at Volumio but this isn't clear about Tidal support..

I am not a Techie! at all!

and I would like to use the iPad and an I phone to use remotely..

Any suggestions please??
