FWIW, I did look at the Clarett range as well (2pre and 4pre) but they did not include SPDIF ... So, I went with the Gen3 Scarlett.
.
What does or can SPDIF accomodate, exactly? I didn't know what SPDIF even was until I Googled it, but even knowing now what SPDIF cables are, I wouldn't even know if those would be something I could even use now of in the future.
