I have a PI3 and the DigiOne not signature. I used Volumio and attached it to the MHDT Orchid Dac. For me the Toslink didn't sound as good as the RCA digital input and I never tried the Coax.
I liked it but as an Amazon Music user I had to move away from it and replaced it with a I5 fanless Windows PC.
For me the MHDT USB driver and supplied USB cable sounded better than just the DigiOne but the Signature with a different DAC should sound pretty darn good.
I really liked the Volumio interface and wish there was a Windows version. For now I remote into it and use Foobar but it's no where near as user friendly as Volumio was
