Not sure I am clear what we are trying to protect against with these speaker cable risers
(a) is it the speaker cables from themselves by creating space around them
(b) I can understand some carpets could cause static but not wood or concrete
(c) my floor is concrete with ceramic tiles and has no bar reinforcement, or pipes or cables underneath.
(d) can cables be pinned to wall three inches above floor (or do walls have same issues as the floor).
“Materials are made of atoms that are normally electrically neutral because they contain equal numbers of positive charges (protons in their nuclei) and negative charges (electrons in “shells” surrounding the nucleus). The phenomenon of static electricity requires a separation of positive and negative charges. When two materials are in contact, electrons may move from one material to the other, which leaves an excess of positive charge on one material, and an equal negative charge on the other. When the materials are separated they retain this charge imbalance.”
"Many semiconductor devices used in electronics are particularly sensitive to static discharge. Conductive antistatic bags are commonly used to protect such components. People who work on circuits that contain these devices often ground themselves with a conductive antistatic strap.
In the industrial settings such as paint or flour plants as well as in hospitals, antistatic safety boots are sometimes used to prevent a buildup of static charge due to contact with the floor. These shoes have soles with good conductivity."
I have two short lengths of RF “semi-rigid” with phono connectors on each end. I’d bought a couple of secondhand bits of Meridian 200 series kit and the chap had made them to run between two of the boxes
Build ‘em from Lego?
These under the S-V are part of the complete kit, but you get the idea.
EDIT: From a quick check on Bricklink, you could get the parts for one bracket (the smaller one) for a couple of quid + pp (say around a fiver per bracket) - cheaper than many cable risers/lifters I’ve seen!
Beyond having my SL interconnect hanging off a wall mounted diffuser in free air in cable ties and otherwise complete cable separation, I did try wooden cable lifters for my speaker cables extensively. With my speakers on Townsend Podiums I did in the end decide, that it actually didn’t make any difference. ATB Peter
PS. This however did….
A bubble of electrons will form before the rubber band, and it will continue swelling and eventually will explode, and then who knows what the consequences will be!!
