My Profiler is from about 2014 so doesn't have the option to set SPDIF to slave. At the moment, this works fine with my SPL Crimson and I definitely prefer the sound of SPDIF over the analog output.
Now I'm looking to upgrade my audio interface and since I already have some UAD DSP on PCIe, I'm looking at their product range. The Apollo x6 is the only one with separate SPDIF on RCA so I would like to use this with the Kemper, which would keep the option to add extra i/o on the optical ADAT some time in the future.
It seems that I should be able to use the Kemper as SPDIF master but from what I'm reading about the new Apollo products, I would then be losing the advantage of the new super tight clocks they've designed. So I'm hoping there's a SPDIF board I could swap out or similar.
Does anyone have any experience around SPDIF here? Has anyone upgraded their Profilers, if this is possible?
