Tiny bridges everywhere, but why?

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.

Take a loot at my system https://systems.audiogon.com/systems/8367   

This system is tweaked to the nine's. Every single one makes a difference, some big some small but it all adds together. Take away the tweaks and this is just another average system. For every tweak you see there are more hidden from view. Also for every tweak you see there are three or four more that were tried and either failed or were upgraded. What you see here is the best of the best.   

Look close, every single wire is elevated up off the floor. There is a specific product called Cable Elevators that 30 years ago was the first to be really good at this. More recently the last several years have seen more audiophiles and manufacturers catch on. Yeah, 30 years and only now.... that is how slow most are to catch on. Happens with everything. Stick around long enough you will see.   

Cable elevators is also a good generic term for anything that gets em up off the floor. The original Cable Elevators are really ceramic insulators made for telephone poles and power wires. Generic ceramic insulators can be found on eBay, they are all virtually the same in terms of performance so search out the deals. Look close, you will see different ones in my system. The big ones under speaker cables are Cable Elevators, all the rest are generic ceramic insulators.    

As for how they work, they all work on a combination of vibration control and reducing static electricity and dielectric effects. I know it is these three things from having tried many different approaches over the years and knowing what works better and what doesn't.   

As far as how well they work, read the comments on my system page. I have demo'd mine and everyone is surprised, the effect is not subtle. Mine however are off the charts tweaked. The ceramic insulators have a thin coat of TC, and the cables are all supported on rubber bands. Remember, vibration control. The best vibration control is isolation, the best of which is by springs. Rubber bands are a cheap effective substitute for springs. You just have to play around a bit to find the right thickness and tension to support each cable so it is free to bounce. These are under power cords and interconnects too.  

Keep in mind the main function is to elevate, and isolate. The only one I know of that uses anything like my suspension system is AudioQuest, and even then not really it uses fishing line which is too tight to isolate. But there are elevators like it that can be tweaked to be good like mine, once you get the hang of what you are doing and why.  

Nope, you don’t need to fork money for fancy ‘audiophile’ cable elevators. Cardas makes inexpensive cable lifters,

But before you spend any money, try lifting your cables off the carpet by using styrofoam cups and see if you hear any audible improvements :-)
