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.

@lowrider57 Exactly what I was hoping to learn. Thank you.

@onhwy61 LOL... I know. Baby steps. I am far from final setup. I have to paint the room, put up the treatments, etc. Asking questions now so I can get to the end result of listening. I am also home auditioning steamers / DACs, so swapping is a constant thing. 

@lalitk Thank you. In hindsight I wish I had treated the room before AB'ing pieces. A well established echo needs to get squashed asap as most tracks sound like I'm in a great hall with high frequency reverb... not pleasant! I only have a 1m ethernet (Merging) cable from the router in my photo. Do I really need something for it?
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.
