What is recommended by the Kemper tech team for how to record . I had been using TS cable for recording for a while before I realized it provides unbalanced connection. Then I read about TRS and SPDIF options for recording(TRS to TRS and SPDIF to SPDIF). Then I came across pros and cons for each. Like SPDIF has issue with setting the clock frequency correctly. And TRS has issue with analog-digital conversion and whether it can faithfully reproduce the original signal.
So in general, what is the recommendation for which route to go. Assuming that reamping is not in the consideration at this point.
