Using an EMMlabs XDS1(v2 or v3) as a transport for an EMMlabs DA2 dac?

If I wanted to spin discs, is this advisable? Would Optilink be the best connection?

I figured my XDS1 would be connected by EMM Optilink cables to the DA2 for discs,
and then my computer (or maybe a server) would use USB to connect to the DA2 for files.

Any comments on this proposed configuration would be welcome. Thank you.
