There are soooo many variables. Coax output, cable, and input implementation etc. Same with optical variables. Do experiment with what you can and use what sounds best to you.
In my own rig after trying 3 coax (silnote, HF Reveal & Acoustic Revive DSIX active) and 2 optical cables (both plastic & glass), on both types both with and without an ifi spdif ipurifier, coax bested optical for both music and video. Since my DAC uses no muting, using the ifi caused a loud zap every time I switched sources (node2) so I left it off. The active AR coax cable sounds most musical and real to me on everything. Good luck!
