I’m proud to use Volumio since so far !
I have more then one Raspy DAC combination, the one I prefer and I use is the DIGIBERRY, specially powered with a power bank trought Raspy standard USB port !
The result is INCREDIBLE !!!
Thanks Guys for the effort ! I have been so long seeking for a decent solution to play files and the combination you provide is something killing the majority of HIEND transport unit I have tested until now!
