Tiny bridges everywhere, but why?


As I am getting closer to my first "complete" system, I am starting to research and get opinions on smaller tweaks. The cherries on top, so to speak. The term "smaller" covers the size, cost and possible impact to SQ. 

I do not know what they are called but I am seeing all sorts of devices holding up cables. Don't know why but they remind me of Navy Seals running out of the ocean with a telephone pole over their shoulder...

Thanks to this forum I have learned that everything in some way impacts SQ, so whatever these thingamabobs are called, do they impact SQ or are they a form of cable management? Both? Do materials matter? Am I going to have to splurge on rosewood versions treated with stain containing ash from one of Jerry Garcia's guitars, or could I use old shoes for now to accomplish whatever mission these fulfill?

I could have Googled this topic, but I want to hear from you - Your experience, choices, etc.

For Halloween I'll set up the Jacob's ladder which is 120v -15 kV at 250VA.  An old lighting transformer.  Fun stuff.

As far as LV insulators go I dig the old glass style  Those ceramics cut like a razor blade if broken or cracked, far worse than glass.

Not sure I get why there's a need to isolate/elevate 2 conductor LV cables with a shield wrap.  What exactly would one be coupling to if left on the floor that negatively affects sound quality?
The OP has an interesting query here.  Can't say I've ever seen or heard of elevated audio cables before. 

Wire management is handled using cable trays.  Your local utility uses miles of cable (and cable trays or underground conduit) in every substation for SCADA control and other sensitive switching control. 

The electrons know where to go... I'd be more concerned about external EMF than cable vibration at miniscule voltage potential.
