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've had that suspicion regarding that lava lamp lurking midst the meticulous...but imh it's just a mcguffin....covering a scratch, perhaps....;)

They are meant to avoid vibrations in the cables. There’s no scientific proof or explanation though that mechanical vibrations have any influence on the transfer of electrical signals. And by the way ... a length of cable that hangs between two spacers has an ’Eigen frequency’, like a guitar string, on which it will oscillate, which actually makes vibrations worse.

But there are people who claim they hear an improvement in sound, and if they do, then that’s wonderful.

If you want to lift your cables from the floor, kitchen sponges work fine as a spring / damper combination. They set you back about $1,-. You can also opt for the ’official’ floor spacers, at prices of $10 or even $100 a piece, but you only need those if you like their looks better.

Cheap ones are called 'cable lifters', more costly are 'Cable Elevators'.  Note the capitalisation adds further perceived value.

But anyone tried gold-plated cable lifters?
If there's an improvement, you can move up to solid gold.

Bah.

The floor of my listening room is concrete and it is underground, and my house is in the middle of a hundred acres in rural Michigan. I have no detectable noise from anywhere in the room or anywhere, including the AC power lines into the house. Zero noise anywhere, nothing measurable even from the components that make up my system. Has this hobby taken a turn towards the dark side? What about listening to, and loving music? Or is that just an afterthought on this forum?

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.
