The Audient ID14 only has S/PDIF In on TOSLINK (switchable between S/PDIF and ADAT). It does not have AES/EBU or S/PDIF output so you can't reamp purely digitally. And you would need a TOSLINK to coaxial adapter. So personally I'd avoid that interface.
The lack of AES/EBU etc. on many interfaces frustrates me. An example being the UAD product line. Some UAD interface have one in and some have an in and out, and that's supposed to be enough.
Sweetwater has a product finder that lets you specify interfaces with digital ins and outs. e.g. ....

One example I'll point out is the MOTU Audio Express USB / FireWire Audio Interface. That has S/PDIF coax in and out for ~$395. MOTU seems like the Rodney Dangerfield of audio interfaces. They make nice stuff but don't get as much respect as I think they should.
BTW if you look at the next tier of pricing, a nice interface is the RME Fireface UCX II including because it has both S/PDIF input and output, and AES/EBU input and output (and those can be used to do S/PDIF if you want just with a cable adapter) and (single port) ADAT In/Out for ~$1,500.
Once way to go for higher-end interfaces that have ADAT In/Out is to use an AES/EBU to/from ADAT converter. RME used to make a range of them, ADI-4 DD, ADI-8 DD, ADI-192 DD, and they do AES to/from MADI etc.
The solution for me is an RME ADI-192 DD going ADAT into an ADAT to MADI box and then a MADI interface. That gets AES/EBU Out to a monitor controller, and AES/EBU In and Out to a couple of Eleven Racks and a Fractal FM3 (S/PDIF out only), and I'll be adding a FX III. That's more than you are asking about but I got so frustrated with lack of digital I/O on many interfaces and I will never go Pro Tools Ultimate/HD (but for folks who are there they have great AES/EBU IO options).
