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.

I wouldn't spend much money or time fooling with cable lifters but it does make things look a bit neater. They do absolutely nothing to your sound so no need to worry they might cause a deleterious effect.
@lalitk Thank you. I will experiment with various household items. Ceramic coffee cups should do for this.

@millercarbon Very impressive. Thank you for the extensive explanation and years to get to where you are. Congratulations. Funny, I thought you had a Jacob’s Ladder until another pic showed it was merely a floor lamp. :) I wonder if some day you will admit that the lava lamp is the true secret sauce.

So far I’ve learned they are called elevators and they will make a difference. I am close to the point of experimenting with these. I have a full room treatment order on the way from GIK. My hope is that a treated room will best allow me to hear the subtle and not so subtle affects of my tweaks. This $tuff is $o much fun!
@djones51 I look forward to testing this. So far I've been super skeptical about everything and I have seen the truth every step of the way. This however, is a different realm of things "not plugged in". Isolation things I look forward to trying on for size. 
What other tweaks have you tried? There are many that are higher than cable lifters on the performance list.

@lowrider57 I am nearly tapped-out for the year in terms of funds for big tweaks like cabling, for example. I am a month or less away from committing to a steaming / dac solution and the room treatments were not cheap. That said, I can only afford to play around with inexpensive tweaks like elevators and anything else people may suggest like perhaps that liquid you can paint onto the ends of cables? I’m up for anything but started here because I’ve seen all kinds of elevators used in nearly every system photo, most of which appear to be wood. My guess is that this could be done on the cheap and suggestions are streaming in, with thanks.
