Cable management. Which cables to strap together?

I figure power cables are ok to velcro together but what else can I sling up without deleterious effect?
I’m thinking you’ve reached the point where people are afraid to open your posts.

Do you know what a snake is?
That's the way signals travel around in performance venues -- and in the recording studio
Otherwise, crossing at right angles for anything carrying AC (and the music signal is AC, of course) and/or as far apart as possible is a best practice).
Practically speaking? Why not try and see if you can detect any difference?
