TR or TRS cables?to connect to an apollo audio interface

Since I bought the Kemper Stage I have always connected the Kemper using a SPDIF cable, but now I want to connect the Kemper with TR or TRS cables, my question is, what type of TR or TRS cables should I buy to connect the Kemper to my Apollo Twin?

I was reading that some people use TR cables and other people use TRS cables

if you want to use the XLR outputs of the Stage you should use XLR to TRS cables. All the other outputs are unbalanced and should be connected with TS cables.

thank you for the reply!!
