Let me explain it to you "dude". Voltage is nothing more than the potential to do work. It does not mean any work will be done. VELOCITY of electrons is not a measure of current (current which is the flow of electrons - charge carriers to be most accurate). You cannot "impede" voltage. Saying something "impedes" voltage is akin to saying something "impedes" height (i.e. potential gravitational energy). AGAIN, velocity of electronics is not a measurement, well of anything in this particular case. Current is charge carrier flow rate past a certain "point" in space. Speed of those carriers does not come into play, no more than saying the speed of water in a hose is 25 meters/second tells you how much water is flowing. Resistance does not impact carrier drift speed, but current density does (for a given class of conductor, say copper wire, with a defined number of free carriers). If you want to be pedantic, in a given system, resistance is at some level a measure of available charge carriers, so for a given current, which translates to current density, resistance could impact the effective drift velocity ... You can't impede voltage, you can only impede the flow of charge carriers (and again, to be most accurate, you can only enable it or not enable it). Whether there is air between two electrodes, or a resistor, the voltage does not change, just the ability to move charge carriers. Do you know why the ampere is a fundamental unit of measure, and the volt is not? Your confusion about current and voltage being "the signal" likely comes from a simplistic view of electricity and physics. I see that difference regularly ... say between the knowledge an electrician has w.r.t. electricity (which only needs to be basic), and that of an electrical engineer and/or engineering physicist who must have a deeper understanding of the concepts as they often work at more fundamental levels. Dude, this is not my "first rodeo". Unlike you, I have been doing this for oh, about 25-30 years, and have had to educated the uneducated such as yourself many times. I would suggest not trying to bully me. It won't work. You are not equipped with the tools. geoffkait17,588 posts10-21-2019 3:47pmYou’re all wet, dude. Let me explain it to you. The fuse impedes voltage, not electrons. The velocity of electrons in copper wire is the same regardless of resistance. As I stated already, electrons are not the signal. Current and voltage are the signal. That’s why wire is directional - because wire - including the wire in fuses - impedes voltage a little more in one direction compared to the other. Follow? I realize this is your first rodeo so I’ll cut you some slack. |
Buddy, Some introspection here, you are harassing me. I am telling you to stop. YOU have the choice whether to stop harassing me or not. AGAIN, INTROSPECTION. I am threatening to treat you the way YOU are already treating me. YOU are actually harassing me. STOP. I have already reported you to moderators for doing this. I don't like doing that, but since all you are doing is harassing without bringing anything, literally nothing to the conversation, then YOU need to stop. I expect moderators will deal with you, but if they accept your harassment, then I will respond to YOU accordingly. I was previously a member of this forum for many years, but deleted my account when I got my last venture going. I don't remember your style of harassment without bringing anything to the table being tolerated. clearthink902 posts10-21-2019 4:32pm roberttcan" If you keep harassing me, I will respond in spades.

The measured difference in voltage drop is a symptom or hint that wire is directional, I.e. asymmetrical. 🔜 The lowest voltage drop will occur when the fuse or wire is in the preferred direction, in terms of sound quality. And the wire or fuse will always sound best when it is in the correct direction. The speed of the signal is near light speed in copper. That is because ...drum roll.. the signal is photons, not electrons. If the electrons were the signal the whole thing would not work. You know, since it takes one hour for the electrons to travel one meter. That’s if the circuit is DC. Obviously in an AC circuit the electrons have a net velocity of Zero since they go back and forth along with the current. 🔛 |
You just sit at home and make this stuff up don't you? Drum roll ... it does not matter how fast the electrons move ... they all move at once. It like a water hose or pope that is already full of water. When you turn on the tap, you don't have to wait several seconds for the water to come out, it comes out near instantly (well function of the speed of the pressure wave .. note how I use actual technical terms that are associated with the effect). The speed is about 2/3 the speed of light. Again, quite obviously you are reading things you don't understand, mixing up what things mean, then misapplying it to other things. The thing that travels near the speed of light is the electromagnetic wave. I am not sure you understand what a photon is. Electrons emit photons when they transit from a high energy level to a low energy level, but that is not what the "signal" is. Are you now confusing transmission in copper with lasers? ... or are did you read a Feyman text but not understand it was an analogy, not an actual description of what occurred? Electrons could emit photons in a wire (and would), but that is not how current flows. This is just so whacky I am not sure if you are trolling at this point. You can't really be this off -base can you? It's silly. The electrons are not the signal ... the electromagnetic wave is, but that electromagnetic wave uses electrons (effectively) as the carrier for that wave and sweeps them along, not at the wave speed, no more than air needs to move at the speed of sound to transmit sound. It takes 1 hour at a current density of about 10 amps/mm^2 in copper near room temperature ... yes I do. geoffkait17,590 posts10-21-2019 5:17pmThe measured difference in voltage drop is a symptom or hint that wire is directional.

Now you’re getting close. The signal is an electromagnetic wave. Obviously, since the signal travels at near light speed. And signal must be photons because all (rpt all) electromagnetic waves are comprised of photons. And you don’t have to be a rocket scientist 🚀 to see electromagnetic waves must be photons since photons are the only particle that travels at light speed in a vacuum and near light speed in a metal conductor. That’s precisely why satellite communications signals (electromagnetic waves) travel at light speed in a vacuum. That’s why there’s a satellite delay for synchronous satellites. Follow? |
You are improperly applying quantum electrodynamics to our EMR discussion, mainly because you don't understand it ... and frankly, NONE of this matters to fuse directionality since the field, whether classical physics based on quantum based, still moves in both direction across the fuse in equal magnitude. You are a square peg/round hole sort of guy, even though we are talking about apples and oranges. If you want to be pedantic, QM does not at this point adequately described many aspects of conduction, i.e aspect of super conductivity, etc. are not adequately addressed, so your "all must be photons" is a leap you are not qualified to make for conductors. Tell me, if the field travels outside the conductor, and the energy is outside the conductor, where are the photons generated and received? .... 10-21-2019 5:58pmNow you’re getting close.

Why? Because you are starting to realize that you can't just throw up some terms in hopes of baffling me with BS? ... Energy passes through that fuse in both directions ... it has to. The voltage potential reverses direction and the EM field must change direction as well. Electrons move in the fuse in both directions, and the EM field in bulk will be the same. Add in that most power supplies are symmetric for both polarities of the AC line. Energy is (line feedback excepted) transferred only from the AC source to the equipment but sometimes it enters through the fuse, and sometimes, the fuse provides the exit path. Either way, it is always there, and always has an impact no matter the polarity of the AC. It is always acting as an element in the circuit, in both directions, and equally. geoffkait17,596 posts10-21-2019 7:57pmThis conversation can serve no purpose any more. |
Theoretically, as I noted, transmission line effects are possible, but would be at such high frequencies as to have no possible audible effects. Far far more likely, would be simple, and practical effects, not geoffkaits physics babble. Fuses and fuse holders are mechanical devices. It is possible that the combination of the fuse shape and the holder shape is more conducive to lower resistance in one direction. However, don't get caught up in the trap for AC fuses that less resistance is always better. Ditto, fuses are thermal devices, a better mechanical connection in one direction coupled with a fuse defect resulting in asymmetrical heating could cause more thermal modulation in one direction. However, unless the fuse is pushed to its limits and the amplifier has some serious serious design issues, thermal modulation of the AC fuse is not going to be audible. |
I am going to go out on a limb and say you have NO formal education in physics or an engineering field deep enough to give you knowledge in this area ..... That is why you think you know what you are talking about, but don't really. You are out, because you cannot win this argument. You are out because you cannot bully me. You are out because you are wrong. That you would even bring up quantum effects when discussing the directionality of a fuse means you don't have even the most basic understanding of circuits. Yes, please go, you are adding nothing to this conversation. HOWEVER, unlike you with your half-baked physics babble, I have actually posited some REAL WORLD ways in which a fuse "could" behave different if inserted in a different direction. It's amazing what actual experience allows one to do when coupled with the theoretical knowledge to use it. geoffkait17,597 posts10-21-2019 8:55pmSince you ask you have shown you don’t know the difference between a field and a wave. Or between an electron and a photon. And you’re unwilling to learn. You are a classic pseudo skeptic on a mission. For those reasons I’m out. See you in the funny papers. |
I could never understand why people who are not engineers or physicists pretend that they are or Audio forums. Anyone can read the posts that I am making here and instead of a few hand-waving lines, my posts are detailed, I can use REAL numbers where warranted, and I don't run away when pushed. If you have to bring up classical or QM physics to justify your belief about a fuse, you have already lost the argument. You don't get even the most basics of the topic. geoffkait17,598 posts10-21-2019 9:10pmGee, are you looking in the mirror? I was thinking the very same thing of you. |
Keep posting and making a bigger fool of yourself. Most people are not dumb. They will read your word salad, and then they will read my well thought out, detailed, and articulate posts. They will know exactly who the charlatan is, but please if you wish to remove all doubt, you keep doing you. geoffkait17,599 posts10-21-2019 10:52pmIf you went to school, which I seriously doubt, I suggest you run down there real fast and demand your money back. |

there is this forum where you get to do it for free You see SR (Synergistic Research) aren't stupid they don't post here like other manufactures do to back up their wares in any conflicts, they know they become liable then, get the stupid shills to do it for them for them. Because they know if someone is seriously injured trying the multitude of different colored mains fuses in different directions doing a/b as fast as they can, that someone one day will forget to unplug from the mains and die. And if they don't post here they are not liable, only their stupid shills are (which will plead insanity anyway with proof). Cheers George |
you'd think for the money some of these fuses cost they could design a really good breaker so if something does go bad your not out the fuse just reset it (fix the issues of course) and go. seriously there are many small form breakers out there (hell look at the aircraft industry for example) so why not make a mini breaker that is Audiophile quality, buy once forget. I'd convert my fuse holder to a breaker in a min if it was better sounding and resettable. $200-$500 fuses seem ridiculous for the money for what you get IMO. not talking about sound quality here just what you physically get for the money seems small IMO. No pun intended. kind of like cartridges oh oh opened a can a worms there sorry. not really ;-) glen |
Or get appropriate safety testing done .... assuming it was not already when it was called something else. glennewdick946 posts10-22-2019 5:59pmyou'd think for the money some of these fuses cost they could design a really good breaker so if something does go bad your not out the fuse just reset it (fix the issues of course) and go. seriously there are many small form breakers out there (hell look at the aircraft industry for example) so why not make a mini breaker that is Audiophile quality, buy once forget.

geoffkait "Getting back to reality for just a moment, aftermarket fuses are not $200-$500. Cut me some slack, Jack. One or two are $200 + The new Orange fuse is $150, almost all the rest are around $20-$50. Check it out, Bubba! If you want to be an audiophile on the cheap just flip your Littelfuse around. " Ok a little exadurated there admittedly but you get the point. I wish I got paid in US$ though, we Canadians pay 30-40% more for much of this stuff. the SR Black fuses are on sale right now at Parts Connxion for $160 Canadian Blues are $150. That said I did notice more other brands at way less money Furtec's for less then $50 so the fuse business has matured since last time I looked nice to see prices coming into the reasonable realm. sorry for my sensationalism, really should refrain from posting when board at work lol glen |
