Shanti has two separate 5v rails which is most appropriate for their DigiOne Signature transport, with a “dirty” SBC galvanically isolated from a “clean” SPDIF HAT.

This is a terrific sounding combination which could, in theory, use either Audiolinux or GentooPlayer OS to implement Diretta at some point. I’ve not personally done it that way because I had moved on from 5200SE to DSP9 by the time I left Roon’s RAAT for Diretta, and the 9s take AES/EBU (not SPDIF).

EDIT: Actually, the 9s can be made to use SPDIF -but it’s a more complicated setup and I like the sound of AES.
