Is there any truth to the direction electrons flow thru a fusible link and does it matter? how about the color of the print on the fuse body? Please read the ad info from the link below. I's really comical.
https://www.synergisticresearch.com/fuses/orange-fuse/ (https://www.synergisticresearch.com/fuses/orange-fuse/)
Gezzzz. I guess I'll just stick to my fuses which cost less than $5.00 usd.

"Audiophile" is all you need to know about it.
It's a curious market; it's set up to not just allow but indeed encourage self delusion, and strictly discourages anything that might break the lie -- like double-blind testing. I guess, since the customers are generally fiendishly wealthy, one might find a certain justice in conning themletting them con themselves, but I wouldn't exactly call that a moral imperative...

2nd Stage Rev. 2.0 Molecular realignment process
Great, I cannot wait to get some of these fuses. I need to upgrade from these: https://www.ebay.de/itm/181509391782 (https://www.ebay.de/itm/181509391782)...They simply cannot be as good as they cost only 22€ / pc.

I was expecting to find something like this at the bottom of the page:
Frequently asked questions.
Q: Are fuses directional?
A: Yes, fuses are directional. Electricity should flow from the left to the right when you view the fuse. If you do not know the direction of flow you should listen to the fuse inserted in both directions. One direction will sound more detailed. This is the correct way.
Q: Do fuses have a burn in period?
A: Yes, most products have a settling in period. The first 200-300 hours of use are the most crucial.

Burn in for audiophiles only consists of music playing, if you want to "burn-in" something with DC or even a sine wave, they don't consider it good enough.
But yeah with 1 million volts I'm surprised the cable doesn't physically burn to a crisp.

You missed the most important feature:
SRX speaker cables are an exploded geometry with ten individual pure silver cables running in parallel separated by carbon fiber discs to eliminate cross-talk between conductors.
Apparently, with:
with Silver Matrix Conductors in a Teflon dialectic
Some Teflon! It can differentiate between the true signal and the rest of it. Clever.

Geez, I've spent my life working on projects to pay my bills, but now know that I've defiantly been in the wrong business. A friend of mine has bought into this fuse idea and has just plunked down $1200.00 for a pair of 12AU7 tubes. You know, the tubes that used to be used in most all amps of that time. We used to use these tubes for target practice in my younger days. He really insists that his sound quality is much better with his super expensive "directional" speaker cables too. Such is life.

Not that hard to have music at a high voltage.
https://www.youtube.com/watch?v=nH-3TdWI-yI (https://www.youtube.com/watch?v=nH-3TdWI-yI)
I suppose if you wanted to market the cable as "high voltage burned in", you could suspend it in the air on nonconductive ropes and connect all conductors at one end to the Tesla coil and provide a discharge path at the other end.

You mean the "cloverleaf" shaped one, not the ordinary "jug plug"?
More to the point, why on earth do they use those bloody useless "barrel connectors" for the low voltage side, instead of a plain old 2 pin rectangular connector like CB radios & the like used to use?
It's not that they need a jack which switches, as charge/not charge is all done electronically these days.
-
hey quick question.

The same reason figure 8 is used on metal-chassis appliances: it's cheaper. Mickey-mouse/cloverleaf/C5/C6 IEC cables only need to use wire rated to 2.5A, not 10A.
More to the point, why on earth do they use those bloody useless "barrel connectors" for the low voltage side, instead of a plain old 2 pin rectangular connector like CB radios & the like used to use?
Do you have a pic of the rectangular connector you're reffering to? I think I've seen lots over the years, including ones that take mains instead of LVDC.
I know there are some standards from the 1990's about round barrel connectors for power (https://en.wikipedia.org/wiki/EIAJ_connector), not sure if there is more history behind that and standardisation of them.
One benefit: don't have to look when plugging them in, very easy to do by feel and rotation doesn't matter.

If they're so freaked out about mains power and the AC to DC power supply, why not design all the audiophool stuff for DC power? Power it all from a big battery bank. Ultra pure DC power. For all the money they pay for quacky power wiring you could probably get a decent bank of pure DC and just let the damn thing re-charge overnight.

But those DC electrons wouldn't be pure DC. They were once AC. It would require yet more audiophoolery stuff to replace every tainted AC electron with a pure, sonically perfect DC electron.

Back when digital cameras were new and very expensive, a colleague borrowed the company's highest resolution device - 640 x 480 (!) - for the weekend. He came back in on Monday with his tail between his legs. He said he thought the different sizes of barrel and pin were always keyed to the voltage / polarity, so he merrily plugged 12V the wrong way round into a 3V (or whatever) port. Naturally, this provided all the opportunity the magic smoke needed to make its escape.
I don't recall the aftermath. Both he and the then-boss passed away some years ago. But not, I might add, as a direct result of polarity / voltage errors.
-
Power it all from a big battery bank.
But wot about the noise from the chemical reaction in the battery ,that will cause audio distortion.Of course i can sell you a device in a fetching black box to cut down the noise,for a price.

The ones I'm thinking of were used in some CBs (not all), & from memory, a "standalone" car cassette player I had a few years before that.
They were definitely rectangular, with, from memory, a narrow keyway one one side, different pin spacing, & smaller pins compared to the "binocular" type connectors used on electric shavers.
Some ham radios used different 12v connectors which you could butcher the shaver ones to fit, but hams were smart enough to cut the mains plug off before they used them.
The one AVGresponding shows would be OK, too, but maybe a tad bulky.

One benefit: don't have to look when plugging them in, very easy to do by feel and rotation doesn't matter.
You often have to wiggle them to make sure they are connecting, though, & the jack inside the laptop is incredibly flimsy.
Yaesu, for some reason, delighted in having the positive on the barrel outside for their handheld & portable radios.
This would be OK, if they are operating from, or being charged by, a power supply at home, but a bit problematical if used in a car.
My old FT290R was, apart from being a bit low on output power, ideal as a mobile, as well as a portable transceiver.
The problem was, if you accidently dropped the lead in the usual negative earth car, it would perversely not fall on plastic or carpet, but seek out any bare metal, delivering a nice "zap", scaring the living bejabbers out of me, apart from sometimes blowing a car fuse, or if not, scarring a nice piece of metal trim.

Every audiophile has got to have one of these nylon UFE receptacles that can be had for under 5 bucks at any big box store. One can tell the super quality difference between the orange, blue and black ones. Just ask them.

I have some of those PTFE cables, got them for free, so took them apart and used the individual cores to make test leads. Works well for that, as the resistance is low, and if you have an oopsie and overload them they just get hot, and nothing else, though you probably will be replacing the banana connector on the end, as it likely has melted.
-
Teflon or PTFE actually will sustain a flame once it starts burning. Try lighting some Teflon pipe tape, but keep away from the fumes. I've heard that Teflon emits Fluorine, which is harmful.
|O |O
-
Elemental fluorine isn't so much of a hazard (as there's plenty of carbon for it to stick to already) as the decomposition products, including lovely chemicals like PFOA (perfluorooctanoic acid -- an 8-carbon unit of former-PTFE with an organic acid group on the end). Lots of carcinogens in there.
Y'know, I wonder... I wouldn't be surprised if the safest, most thorough way to dispose of PTFE is to incinerate it -- very hot, in the presence of steam, yielding HF and CO2.
...Ah and yep, it is indeed fine, in fact it doesn't even need super high temperatures to do it:
https://www.gore-tex.com/sites/default/files/docs/Chemosphere_Incineration%20Study_Executive-Summary%20(002).pdf (https://www.gore-tex.com/sites/default/files/docs/Chemosphere_Incineration%20Study_Executive-Summary%20(002).pdf)
I mean, 1000C is a good bit more than your average charcoal grill, but it's pretty ordinary for enclosed fires and industrial processes. That's a typical kiln temperature for example.
Tim
-
Common for a lot of medical single use consumables to have PTFE as a lining or component in them, because of the biocompatability of inert PTFE with the body. As all is incinerated the PTFE will be burned as well, another good reason why you to not want to live downwind of an incinerator. The other common disposal method is to simply bury it, where it will survive for centuries, along with glass and ceramics.

Marx generators, Vaan De Graff's, Tesla coils, all can generate tremendous voltage. They didn't say it was continuous either, or at how much current.

isnt that a cheap diode?
BTW electrons do not flow.

BTW electrons do not flow.
?
When the electrons flow through the battery they gain energy, but when they flow through the bulb they lose energy as it is converted to other forms like light and heat.
https://www.physics.uoguelph.ca/electron-flow (https://www.physics.uoguelph.ca/electron-flow)
-
A common misonception. its way of visualuisng things but its quite untrue. Current is defined as the rate of flow of charge not yellow balls! Think of the electons surrounding atoms in a conductor as a bucket brigade for charge. One of these electrons picks up some charge which is picked off by the next and so on.
It more like pushing on the end of a rod. The force is tranmitted but the rod remains unchanged. It more complicated than that of course.
Only few electrons in a wire are actually moving at all. The ones that do move at a snails pace, or less.
The false idea that electrons flow is so widely regurgited that its taken as physical fact -it is not, its an analogy thats a bit better than the water one.
This idea seems to be deeply upsetting for some, not least to vacuum tube enthusiasts. Its the charge created by the hot cathode that is acclerated to the anode not the electons themselves running about. A hot cathode does the same job as a cold cathode. The heating allows us to use a much smaller cathode area to obtain the same effect as a cold one.

The heating allows us to use a much smaller cathode area to obtain the same effect as a cold one.
So the "charge" from the hot cathode in a Pentode valve impacts the anode with sufficient force that it knocks off some secondary "charges" that are collected by the [Edit:screen suppressor] grid, preventing the characteristic Tetrode kink?
Do "charges" have mass then? :-\
P.S. How do the "charges" in an X-Ray tube work? Genuinely curious.
-
What's wrong with the hydraulic analogy? When one understands atomic theory, one knows that liquid water is composed of *illions of molecules banging around at about 1500 m/s. Almost any flow rate you'll encounter, is a small fraction of this, and so we can make the same observation that pressure is transmitted from molecules bumping into each other, not so much the overall flow; and that the dominant motion is internal and random.
It's an uninteresting argument, and worst of all, doesn't illuminate anything to the reader. So what if it's mostly random motion, does that just mean it's getting hot or something? No, that's just thermal energy. Oh, and it's too small to see. Well so what. (Well, yes actually, it is effectively the origin of resistance. But proving it gives a proportional [Ohm's] law, is much harder. Or understanding the sequence of facts that are required to derive such a law -- that's whole-ass statistical mechanics, arguably. :o )
What's interesting is when the charges are "free" to flow, i.e. in free space under the influence of fields, ballistically, rather than damped out by random motions. Then we find a V^(3/2) power (Child-Langmuir) law, we find mass and we find everything that we expect as a consequence from that (i.e. all the electron-resonant microwave tubes).
Cool fact, the electrode (especially grid) capacitance of a late model vacuum tube about doubles going from cold, to hot and biased. The cathode electron cloud expands and contracts in response to the grid's electric field, giving and taking energy from the electric field; mass is a conservative property, and so too is the manifestation at the electrode -- reactance. If some of the cloud happens to leave, however, its initial energy is carried off with it -- beam current causes loss, manifest as grid conductance/resistance, however you like to express it. This extends to subsequent electrodes, too: the screen, suppressor, etc. experience a small transconductance, from grid to grid, even when the later grid is reverse-biased (as suppressor or pentagrid control 2). The reciprocal is not true, however: the beam acts as a conveyor belt, breaking symmetry, and thus this is a nonreciprocal property (gm(1-3) nonzero but gm(3-1) zero, or, effectively just plain old interelectrode capacitance because it's not going to be |zero| in practice).
This property is even used to advantage in some types: dual-control pentodes (6HZ6 etc.) and sheet pentodes (6BN6 etc.) can be used for FM discriminator service, where g3 is simply tied to GND through a high impedance parallel LC tank. gm13 is quite small (10s umho?) so the impedance needs to be quite high (100s kohm), but given this, it resonates sympathetically with the driven source. g3 voltage acts to gate the output (plate) current, so the plate current ends up PWM with respect to the phase shift between source and resonant tank. And that phase shift is proportional to frequency shift vs. resonance (for small enough changes in frequency -- for commercial WBFM, the Q needs to be fairly low; like I said, high impedance tank!).
Ballistic transport is also possible in some semiconductors; in others, avalanche breakdown occurs first, but when it doesn't, current flattens out, or even goes negative (as is the case for GaAs (Gunn diodes), something about varying saturation velocity in different Brillouin zones, i.e. the electrons changing directions as they travel through the crystal).

Yes, it's for quantum customers--ones are are simultaneously rich and dumb.
-
For a quantum fuse to be subject to the Schrödinger's Cat paradox, it must be inside an opaque (e.g., ceramic) tube so that the observer throws away information to which he is physically entitled.
With a glass tube, the fuse can be inspected visually without disturbing its state, just like the poor cat imprisoned in a glass cage rather than an opaque Bakelite cage. Room illumination through the glass cage does not affect the quantum state of the radioactive nuclide that triggers the poison.

I thought these were something being flogged by a one-man band capturing the odd credulous sweepings off the floor to make a few bob, but it's enough to sustain an actual company with significant overheads. And employees, which prompts: surely they must realise it's bullshit and they just scamming people - it ain't just one bloke without morals but an entire company of them.

But those DC electrons wouldn't be pure DC. They were once AC. It would require yet more audiophoolery stuff to replace every tainted AC electron with a pure, sonically perfect DC electron.
Next thing you know, they’ll be offering non-directional diodes to unrectify the noisy DC.

Much more intelligent discussion on the topic of fuses, and their potential to affect the sound of an amplifier:
https://www.avforums.com/threads/audiophile-fuses.2348393/ (https://www.avforums.com/threads/audiophile-fuses.2348393/)
After reading through that thread, I came to the same conclusion as poster Phildick: "What you need to consider is how the power supply in the amp works here. The incoming AC is converted to lower voltage DC and stored in large capacitors. On switch on the caps are charged up to capacity and kept topped up. It is the electric in the caps that drive the amp not the mains cable or any fuses on the AC side. So, if taking the fuse out of circuit make a difference the amp must be faulty or badly designed."
I have no idea about the "venerable Audiolab 8000A" but if it's an audiophile product, one must assume that it has a shitty power supply.

I'd thought it would be interesting to see if that "Positive Feedback" certificate for their Orange fuse is real:

Back when digital cameras were new and very expensive, a colleague borrowed the company's highest resolution device - 640 x 480 (!) - for the weekend. He came back in on Monday with his tail between his legs. He said he thought the different sizes of barrel and pin were always keyed to the voltage / polarity, so he merrily plugged 12V the wrong way round into a 3V (or whatever) port. Naturally, this provided all the opportunity the magic smoke needed to make its escape.
I don't recall the aftermath. Both he and the then-boss passed away some years ago. But not, I might add, as a direct result of polarity / voltage errors.
I've seen that a lot, people assume that if the plug fits it will work. A lot of audio equipment in particular gets damaged because for reasons I don't really understand most audio gear uses center negative while most other equipment is center positive.

I always rationalised this as the outer ‘shield’ grounded (-), but never took it for granted!

When I see this audiophoolery I should be shocked and apalled….. but I am not. We live in a World where some people think that Planet Earth is flat :palm:
A fool and their money are easily parted ;D
The people who make this ludicrous Audiophool kit are probably delusional as well so may actually think they are modern Einstein’s where Hi Fidelity Audio is concerned. People can make and buy what they want with their own money though, so these companies continue to exist with little or no official interest in their ludicrous claims.
Has anyone asked an Audiophool how they cope with the fact that the original recording systems that produce the media they play had none of this ‘special’ kit used in them ? Or do they buy ‘special’ recordings on ‘special’ media from ‘special’ trusted sources ?

I don't see a problem there. The original may be magically perfect, or could be atrociously bad, but that's not relevant (and is unfixable anyway). What they are concerned with, presumably, is that stuff they can control doesn't make it worse.

I got the email back very quick about that certificate and that was genuine and issued last December.
Just reread this:
https://www.synergisticresearch.com/fuses/orange-fuse/ (https://www.synergisticresearch.com/fuses/orange-fuse/)
Q: Are fuses directional?
A: Yes, fuses are directional. Electricity should flow from the left to the right when you view the fuse. If you do not know the direction of flow you should listen to the fuse inserted in both directions
.
Say it was directional like with diodes, how is that even possible for the fuse (one component) to be inserted in both directions at the same time like that as what I think they are suggesting?
Speaking of orange fuses I remember these:
https://highend-electronics.com/products/audio-magic-premiere-beeswax-super-fuse?variant=1203927563 (https://highend-electronics.com/products/audio-magic-premiere-beeswax-super-fuse?variant=1203927563)
(https://i.imgur.com/MxfBcP7.jpg)
I question in relation to "electron flow" what effect is that tiny bit of honey around whatever material that is going to do for the sound and what if you insert them in the wrong way?
Like that tiny drip of honey Beeswax on the ouside is going to do anything.
Just found a discussion about these orange fuses on AudioGoon:

I find SR fuses to blow much more easily than a normal fuse with the same rating. After this happening a few times with the Blues I took the advise of Alfred at High End Electronics and bought a slightly higher rating fuse but it too eventually blew. Two pieces of highly regarded equipment this happened with that otherwise have no problems.
No problems with the fuses blowing? Well that says something.
So an orange one of these blows up more than a normal use, that can't be right can it, that it should blow like that to be replaced more often and even with a higher rating but the normal fuses were blowing less then there must be something obviously not right with the equipment.
The two pieces of equipment are so "highly regarded" that it's perfectly fine for them to develop a fault and blow up fuses, that makes them okay and safe because they're "high regraded".

The complete schematic is posted here, you can analyse it for yourself. It's about the most basic linear PSU possible, very typical for the time and probably wouldn't pass EMC if it were tested to today's standards.

Well if fuses are directional, then so must be resistors. So are all the resistors in the stereo amp or other box all inserted the right way? Or all the wiring?
What they come up with is something to sell that can be replaced by the customer. Are they selling directional resistors to replace all the ones in your system? Nope, because most people wouldn't take apart the box and do that kind of work. If they did, they would sell directional replacement resistors. We're trying to analyze the irrational, rationally. It won't ever reveal anything more than people are ... irrational and there are plenty of scammers waiting to take their money.

Dunkemhigh,
Regarding the source material….. I agree but what I was meaning was…. With some audiophiles so focussed on maximum audio fidelity, how do they mentally cope with the idea that the source material is so ‘compromised’ at the recording stage. When people are spending many thousands of Dollars on cables etc, I would expect their minds to implode when they realised how ‘appallingly poor’ the equipment was that actually captured the original audio signal ;D In an Audiophoolery environment that hates anything less than ‘acoustic perfection’ how can a source of less than perfection be tolerated ? It may well be beyond the Audiophile to correct the terrible fidelity issues that they might perceive being introduced by such ‘imperfect’ recording studios but surely that would annoy their amazing ‘sonically calibrated and perfect’ ear drums that they moisturise daily with concentrated Angels tears ;D
The perfectionist can have a very troubled mind in an imperfect World !
And let us not forget the old saying… garbage in - garbage out ;D
Oh you could so mess with an audiophiles head if you really wanted to :-+
To be clear…. We are discussing Audiophoolery and Audiophools here and NOT Hi-Fidelity enthusiasts for whom I have nothing but respect. High Fidelity reproduction of a source material, no matter what the original quality, is totally understandable. Worrying about the electron flow direction in a power supply fuse is a million miles away from the thought processes of Hi-Fidelity enthusiasts and designers that I have met….. they live in the real world and genuinely care about correct amplifier design, component noise figures, crosstalk, harmonic distortion and other specifications that are based upon good science and fact rather than Snake Oil salesman Audiophoolery theories and products.
If a Hi-Fidelity designer asked me to pay £10K for his amplifier because he has spent 15 years of his life perfecting it and hand picked components, based on real testing in order to create the best possible bandwidth, noise floor, distortion, channel balance and separation…. All hand built on very high quality PCB’s with only first grade components of the highest true (not Audiophool) specifications, I might consider his product worthy of such an asking price.
A life’s work deserves just rewards. I still would not spend that sort of money on the amplifier though as I know my poor ‘acoustically abused’ ears are over 50 years old and imperfect ! ;D

Nope, because most people wouldn't take apart the box and do that kind of work. If they did, they would sell directional replacement resistors.
They wouldn't take it apart to desolder a resistor and solder a new one in but... perhaps they might take it apart to attach the stick-on uni-directional e-field tube wrapper. Easy for the owner, and since the tube has to be split to get it on, you can always say they didn't join up the edges correctly if they don't notice any difference. You could make it out of something quite brittle too.
