I have read teo_audio's post from September 25, 2018 at 8:34 am five times so far. I have been trying to gather points from it, minus Richard Feynman's speech regarding some mysterious untraceable experiment. In the end, or at least so far, what I have concluded about that whole post is... "And that is psychology ---not science, not the scientific method." At the same time, someone might argue against proclaiming that psychology is not a science, but that is certainly a matter for some other forum. I am not sure how it all relates to speaker cable burn in period, but I found that post more interesting and informative than most around here. |

Is the hypothesis proposed that there is directionality inherent to wire, built into the physical structure and composition, even before it is ever connected to a voltage source, either DC or AC? Or, is it that directionality becomes apparent only after connection to such voltage sources the hypothesis? If the former, please explain what physical structures are fabricated into wire that determine directionality. Otherwise, everyone here is simply full of it. |
Physically asymmetrical HOW? And how can resistance measure lower at one end than the other? Stupid pseudoscience garbage. Measure a resistor with leads one way, then flip them around, and they measure the same. IāVE DONE IT. I build amplifiers. Fuses, HAH! NO clothes. But then I guess many of you are laughing because I'm somewhat late to this game. Very funny. |

How slow is costco_emoji? Costc_emoji is so slow that after all this time he still doesnāt know what directionality even is. All cables are directional regardless of whether they have a ground. If the cables have a ground the directionality of the wire should be *controlled* to comply with the ground direction. Audioquest does this. Most cable companies do not do this out of ignorance or laziness. The copper on printed circuit boards is not pulled through a die so itās exempt from the directionality rule. But all the internal wiring in electronics is directional. The wire in inductors, transformers, point to point wiring, and all the wiring in speaker crossovers, and other internal speaker wiring. The industry is apparently rather retarded when it comes to the touchy sudject of directionality. And will hear none of it. Very strange IMHO.

@geoffkait The wire in cables and fuses is physically asymmetrical. Thatās why resistance measures slightly lower end to end one way than the other. Guess which way sounds better.My understanding is that the premise is the asymmetrical directionality is a result of how the wire is drawn. I have not looked into whether there are measurements showing a repeatable difference in resistance with wire direction although I seem to remember some here citing the HiFi-Tuning fuse test results as one example. I have seen stranger things and do not doubt there could be a metallurgical basis for asymmetry based on the manufacturing process so I would not refute or even spend time arguing Geoffās assertion of directionality but it is the "sounding better" part where I become a skeptic. There are just too many other things going on in every system for me to believe that a typical person could discern differences in wire directionality by ear. It would be like hearing a flyās wings flapping in the backseat of your car going 60 mph down a gravel road or, in terms of water, the effect of a stick on the flow rate of the Mississippi River, IMO. |

Iāve always cautioned that negative results of directionality, like anything else, must be taken with a grain of salt since there are quite a few things that can and do go wrong with evaluations and make it difficult to hear differences. You know, things like mistakes in the system, hearing issues, and errors in the test procedure. I think itās safe to say negative results for cable directionality are relatively rare over the past 25 years and can be thrown out. How many customers of (directional) aftermarket fuses are there since they first came out 15 years ago? 100,000? Thatās a whole lot of typical people who can hear wire directionality. Itās not rocket science. You listen. Hel-loo!Ā |
"How many customers of (directional) aftermarket fuses are there since they first came out 15 years ago? 100,000? Thatās a whole lot of typical people who can hear wire directionality."As with any epidemiological approach, it would be interesting to see the changes in new-fuse-buyers incidence in general market and their relationship to current marketing trends. Often, probably always, objects of hallucination are related to common names/events surrounding the affected subject. 100 000 new customers over 15 years is between 6000 and 7000 a year, assuming that someone actually knows how many different people bought such fuses. It would be hard, if not entirely impossible, to know how many individual buyers exist. However, given the very specific nature of such a purchase and obvious dedication to the subject, it is safe to assume that each buyer has bought more than one fuse. Which would greatly decrease the number of people interested in fuses and hearing those differences. In the world where number of iPhones may be approaching one billion, a few thousand people who, for whatever legitimate or not so acceptable reason, hear differences in fuses can hardly be considered "a whole lot of typical people". To begin with, people who buy aftermarket fuses are not typical and carry a heavy burden of, admittedly good-natured, potential bias on their findings. |
Geoff, How many customers of (directional) aftermarket fuses are there since they first came out 15 years ago? 100,000? Thatās a whole lot of typical people who can hear wire directionality.Of course, I am skeptical that those folks actually hear the direction of their fuses rather than the psycho-acoustical effects ofĀ cognitive bias or loss aversion based on marketing hype and the fact those items cost more than the "regular" fuses some of us unenlightened folks use. |
mitch2 ... I am skeptical that those folks actually hear the direction of their fuses rather than the psycho-acoustical effects of cognitive bias or loss aversion based on marketing hype ...Skepticism is a good thing. Have you ever experimented with premium fuses and whether they exhibit directionality? That's what separates the skeptics from the nay-sayers. |

So what? Get in line. Thatās why audiophile fuses have been controversial from the beginning. A real skeptic doesnāt keep repeating the same old line about expectation bias or psychological effects, he rolls up his sleeves and investigates. Thatās the scientific method. Of course if youāre just mouthing off and not really interested in the facts of this case I can certainly understand. |

@cleedsĀ To your question - Yes @geoffkaitĀ Yes, I have rolled up my sleeves and investigated aftermarket fuses of several varieties and directionality of those fuses.Ā Bottom line is that I do not perceive differences between those aftermarket fuses and my typical Littelfuse or Bussmann fuses (I do however perceive differences between cables, so go figure).Ā Most of those aftermarket fuses are still in my gear and I have no reason to remove them since I own them, they work, and they don't seem to make things sound worse.Ā My own trials and observations of those fuses and common sense related to the length of a fuse wire compared to the many signal traces, electrical parts, andĀ feet of wire presentĀ in most equipment are what has led me to be skeptical of what others report hearing.Ā However, for clarity, I do not question what they hear, just the reasons why.Ā Also, unlike some others, I am fine with this difference of opinion and feel no need to change anyone else's mind. |
