We all know that signal is flowing through the cables and that most carpeting can develop an electrostatic charge that can zap us (discharge) when we shuffle across the floor when the weather is cool and humidity is low
Does raising speaker cables off the floor really make a big difference?
My cables are laying on the floor (in a mess), would raising them off the floor really make much of a difference? The problem is they are quite wide and too long

It is us that holds the charge when we get shocked, not the carpet. If your humidity is really low, that could be having a real effect on the sound (more attenuation at high frequencies). Get a humidifier. Cable elevators can't fix humidity. |

You have to ask yourself, do you really think the sound stage, which is almost all a factor of recording and speaker/room interaction, would magically collapse due to some exceedingly low level interaction between a cable and the floor? goose390 posts12-18-2019 11:06amWhen we at RMAF this year, there was an A/B demo in the Synergistic Research room of having the cable lifters in and then out. There was an immediate collapse in the soundstage when they were removed. So the wild card in this demo was that the lifters also included an HFT as part of the lifter. Was it the lifter or the HFT? |
Writing something down does not make it true. Sound-stage is predominantly from large scale effects in the recording, the speakers (namely dispersion, smoothness of frequency response, and lack of significant phase irregularities), and how that interacts with the room. Don't need to trust me on that, we know that sound-stages comes from directional / distance cues, and they are dominated by the currently loudest signals. Very subtle things, 100db down, heck even 60-70db down from the signal have little impact on any perception of sound-stage. Anything that "collapses" the sound-stage is a gross significant change, and that is never going to come from cable elevators. Far more likely is what prof alluded to. Slew rate is defined by volume and bandwidth, as is complexity. No miracles there. teo_audio1,292 posts12-18-2019 11:37amYou have to ask yourself, do you really think the sound stage, which is almost all a factor of recording and speaker/room interaction, would magically collapse due to some exceedingly low level interaction between a cable and the floor?All the subtle information we look for with our ears, in a recording, is low in level..so yes..I would expect that the subtle and easy to disturb high slew rate impossibly intertwined micro signals involved in our limits of human resolution ..might benefit from some careful handling. |
Not a big deal, but not all audiophiles have endless funds, and they read forums like these to find out where to spend them. Most never post. Reading of forums far exceeds participation. Wouldn't you rather people who are interested in audio have the best experience they can with the money they have? Why do all these claims breaks down so quickly when eyes are removed from the equation? michaelgreenaudio990 posts12-18-2019 12:34pm |
Some would say it is more akin to religion. Lacking understanding or knowledge, one will make up an explanation to fill in the gaps. Maybe it is akin to anti-vaxxers (and climate change denial), again, most lacking knowledge, will grab onto anything that appears to support their desired world view. wyoboy38 posts12-22-2019 1:02pmIt's like climate change debate or any politics these days--neither side will change the others' mind--but believers can share while non-believers can only bash--and i have no idea yet which camp i'm in on this ! |
But who are the naysayers? Are they the ones that refuse to allow their claims to be tested, or the ones who encourage the tests, even admitting to their own fallacies? I think those honest with themselves, know who the real naysayers are. It is a generally accepted truth that those that refuse to allow their claims to be tested, that avoid all attempts at verifying their claims, and that make up excuses for why those tests won't work (and make up excuses that don't jive with accepted facts), are the ones that are not honest, at least with themselves. nonoise5,200 posts12-22-2019 1:38pmI think there is an awful lot of projection from naysayers as of late. They cling to certain bias diagnosis (from afar) and neglect the ones they fall victim to. |
Some sacred texts never change, no matter what we know or learn. Texts related to science are always being updated as we learn. cleeds2,645 posts12-22-2019 1:39pm There are also fundamentalist zealots, who insist their infallible sacred texts reveal all the truths that are to be known. |
"The chassis obviously closes in the sound stage"? ... huh? The only thing that is obvious is that this is a claim with no merit or factual basis. Do those big transformers have closed magnetic paths and cover shields? michaelgreenaudio1,009 posts12-22-2019 4:22am |
Carpets are often made of one of those "fancy" dielectrics, i.e. polypropylene, and polyethylene, and because it is a open weave, would be similar to foamed polyethylene and foamed polypropylene, which are the best dielectrics for cable w.r.t. low dielectric constant, even better than teflon which is difficult to foam. Teflon is used for high frequency cables because it is dimensionally stable which is necessary for high frequency operation (constant impedance). Wood is a so-so dielectric. Of course a worse dielectric than wood and much worse than carpet would be porcelain what those cable insulators are typically made of. |
Clearthink, If you are going to troll me, which appears to be what you are doing, then you better sharpen your pencil or your Google skills, or go back to school. 1) Polypropylene is the second most common material used for indoor carpets and dominates by a large measure in commercial applications. Note my wording "often". The most common residential indoor material is Nylon. 2) Weave is a somewhat generic term meaning interlacing. A Berber carpet weaves a loop into a backing but does not cut it. A cut pile carpet weaves a loop into the backing and then cuts it. In both cases, those loops are made from .... wait for it ... interlaced (weaved) threads. Your comment w.r.t weave is pedantic, inaccurate, and most importantly missed the point w.r.t. dielectrics / dielectric constants. As the weave of both the threads themselves are open (not tight), and ditto for the overall construction, most of the carpet ends up being air. This would be similar to the foamed construction of dielectrics in commercial cables. Being essentially air, the dielectric constant of the carpet will be much lower than the raw material used in it .. akin to those fancy dielectrics (like teflon) used in audio cables. 3) Porcelain has a much higher dielectric constant than most plastics. That is not remotely debatable. Also not debatable is that purely for an insulator of high voltage, dielectric strength is the critical measure, not dielectric constant. However, where a porcelain insulator is concerned, that is still not the critical measure, since the "insulation" is really not the porcelain itself, except where it is mounted, but the distance formed by the surface of the insulator between the wire and what it is being insulated from. That is why those insulators are usually wavy to increase surface length, or in technical parlance, creepage distance. Porcelain is used because it is strong/stiff, does not break down under sunlight (like most plastics), does not oxidize, relatively impervious to environmental contaminants, smooth surface is self cleaning, is non hydroscopic, and has all those properties while also being very cheap. |
Weave: to form by interlacing threads, yarns, strands, or strips of some material: Pedantic: overly concerned with minute details or formalisms Wrong:
How open or closed the weave (or non weave) defines how close the tufts are to each other which defines the density of the fibres where the cables lie (approx) which defines the dielectric constant. |
