I know the subject might have been already discussed here but it seems many years ago.
I recently got an Antelope Zen Q interface with Discrete preamps and spdif connection, which I never had before.
So I gave it a test with the KPA, comparing the recording of incoming, amplified signal with spdif and with xlr.
My first test for high-gain sound shows me barely any differences between the two. I made sure I selected internal clock for spdif at 48 khz,
which is the same with the interface. Not sure to understand the importance by which one has to be the 'slave' yet.
If I made no wrong, and the difference of sound is minimal, are you still recording spdif for the sake of having more free inputs available?
Thanks for your insights
