Some audio enthusiasts are really paying attention to detail by using cable risers. Cable risers lift speaker wires off of the floor. The object is to eliminate contact with static electricity from a carpet or other connective issues with any type floor material. They can take many different forms both material and shapes. Popular types include notched wooden bridges, ceramic insulator style, and plastic sling type.
But there is an ongoing debate as to whether they actually make a difference in your sound or if they are a frivolous upgrade. Some say they can affect the flow or current, while others say it’s all just nonsense. Below you’ll find out what some of our users had to say about them on our forum.
Tbromgard: Can anyone explain why cable risers do or don’t work to improve the sound? Thanks.
Mapman: Not something I worry about, but some carpets are prone to static electricity, which can only be bad. Also, running wires parallel to each other and in close proximity over a distance is generally not a good idea due to em field interaction, and risers are one way to avoid that.
Rok2id: They do nothing except separate you from your money. It’s called wealth transfer.
Nonoise: The interaction that occurs is when something like a synthetic carpet has cables laying on them. The synthetic carpet’s properties are similar to those used in cable jackets and thus, compete with and interfere with those fields mentioned that travel with the cables signal. They simply smear the signal. Yes, they can be measured so it stands to reason that if something is nearby, let alone parallel with and touching a cable, can interact with it, then it can mess with it. To what extent is debatable but if you have synthetic carpets, then go the extra mile to get them away from the carpet but you need not pay through the nose to do so. I’m lucky in that my Mapleshade Double Helix speaker cables are so taut that they are easily suspended with nothing more than themselves and whatever nearby is handy. If you have wool carpets or wood flooring, I wouldn’t give it any consideration.
Viridian: There is a firm, scientific basis for raising cables off of the carpet changing the way that electrons flow through them. The carpet actually acts as part of the dielectric covering the conductors. Taking the cables out of contact with the dielectric of the carpet will hence change the electron flow and fields within the cable. Of course, the audibility of all this is up for discussion. Personally, my life is too short. But I would never dismiss the idea.
Stevecham: People talk about flow of electrons like water through a pipe but folks, there is zero net displacement of electrons in speaker cables. Stop the voodoo please.
Samhar: I couldn’t hear any difference but they did dress up the wires, kept dust bunnies off the cables, and because I used inexpensive foam elevators that stacked, keep wires separated/organized around the racks.
