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.

Izjjzi,
Careful with cable riser recommendations, their effects are limited at best. Tried it with little to no results. Be careful with certain individuals that will get you charging down deep, dark rabbit holes.
Just another way to spend a lot of money that could benefit you in a different direction. IMHO
+1 what Millercarbon said.

I use the old electrical insulators as elevators. You have some good components… once you did the big stuff… the perfect time to do the smaller stuff. Ultimately it is what can add up to turning a good system into great system. 

Isolation works everywhere. While this is not tiny cost…. If you don’t have a direct line (or better yet, two, consider that. You can get a sizable boost in performance there.
Wait!  If this is your “first complete system” then wait.  Wait until you have lived with your system as is and first develop a solid understanding and appreciation of its sound.  Fine tune speaker placement, make sure all plugs and jacks are very clean, do as Ohnwy61 suggests and live with that sound for some time.  THEN experiment with “smaller tweaks”.  You’ll then be able to appreciate the possible benefits far better.  
The only Jacob's Ladder I know is the Tim Robbins movie. Had to go look it up and, holy cow! That is the LAST thing I would put in my listening room! I mean it looks cool and all, and there are people I would for damn sure love to scare the Dicken's out of with it, but Lord man can you imagine the EMI!?!?!! Crikey!!!
