Some peeps get into the details and they fall in love with grandiose thinking and they fall in love with the technology. Some people purchase electronics because they want to participate in electronics technology rather than experience electronics as tool. It's easy to bait these types. I've seen it when I was a audio salesperson many moons ago. The participant type that's want to buy into the technology and excitement of it so they can participate. They are easy marks for sharks.Why are "audiophiles" so into bullshit is the bigger question....
It is not measurement variation, it is real and repeatable.
And has nothing to do with audio.
I would not have used the word "directional" as that implies something different to me than a wire that looks different from one end than the other (at several GHz).
Enough OT from me.
... or, perhaps, it is like the jocular reference to bugs in Microsoft s/w products as "features"?One could say that directionality is caused accidentally by manufacturing tolerances not being tight enough but its incorrect to say that they are directional by design which they are not. It is and will remain semantics.

Use a kelvin connection to make such low ohms measurements-you'll get good repeatability if the milli-ohmmeter is any good.

To me, "directionality" implies something like an ideal diode that conducts only one way, or a battery that requires you to be cognizant of + and - terminals. That is why I did not think of "directionality" in the context of this thread (aside from the fact that the effects are deep in the mud at audio frequencies; I have measured dielectric traps that cause noise, using a leaf voltmeter to measure fV, but that is well below the audible level).
At high frequencies, imperfections in the wires (and dielectrics) cause "ragged" current flow due to things like surface roughness (at the microscopic level a wire is not perfectly smooth), charge traps and voids in the dielectric and wires themselves, impurities like stray metals and chemicals that can affect the electrical and magnetic fields, and so forth. These matter when wavelengths get very, very small so tiny imperfections matter. That causes signals to behave differently depending upon how they travel down the cable. For cables at very high frequencies, there is not really much you can do in the way of manufacturing tolerances, unless you can make a perfectly smooth wire and insulator at the atomic level with no impurities anywhere. Audio wavelengths vastly exceed the dimensions of these imperfections, unless the cable is flat-out broken, so this is way outside the audio realm.
Connectors are usually the bigger problem, at RF and audio.
To reiterate, for me directional audio cables fall into two categories that I have seen (there may be others):
Please be done... - Don
- Cables with an isolated shield connected at one end. This could be an XLR cable that has an inner twisted-pair for the signal and outer shield, or a single-ended RCA cable that has center conductor, inner shield, and second out shield insulated from the inner shield and connected at one end. Such RCA cables are rare but I have a few; most "quad-shield" is four shield layers that are all in contact for reliability and higher shield coverage rather than having an isolated outer shield.
- Cables that include some sort of filter or "termination" network at one end, with the intent that the filter network should be nearer the source or load.
You have no idea what he said and what it means. I have worked with RF since I was little. I used to repair them for a living. Go ahead and show me an RF cable that has directions on it. Go ahead. We will wait. Until then, then only person who doesn't know what he is saying is you with that comment about directionality and sound changing.

All my cable measurements and even speaker impedance measurements use Kelvin 4 wire method. Yet variations can be quite large due to impedance of clamping jaws. I had to develop constant pressure clamping to minimize it. Fixtures used be cable companies is quite elaborate in this regard.Use a kelvin connection to make such low ohms measurements-you'll get good repeatability if the milli-ohmmeter is any good.
That is improved bandwidth!How on earth can changing a fuse allow for anyone to discern the personality and facial expressions of the performers on a recording? ...
After arguing that some fuses "just didn’t have the musicality of" others, a grown man on another forum makes a strong argument in favor of spending more than $200 per fuse. Of course you can return them if you don't hear a great difference. I quote from about 12 posts down on this thread
https://forum.audiogon.com/discussions/the-new-synergistic-research-purple-fuses
"As my system continues to evolve, there is more body to the music...On vocals, not only do I hear the voice, but I can also discern the personality of the vocalist, even make out their facial expressions.
Percussion is particularly improved, with more dynamics and realism. For example, it is easy to discern the differences between animal skin drum heads vs acrylic drum heads. The correct woodiness of rim shots is amazing.
The piano is tonally correct including the lower registers. A friend brought over a Ramsey Lewis Trio CD this morning that featured a drummer that was using a cowbell as part of his ensemble. That cowbell was in the room along with the entire drumset. You’d have to hear it to understand."
How on earth can changing a fuse allow for anyone to discern the personality and facial expressions of the performers on a recording? What a vivid imagination! And then to distinguish the materials of different drum heads. What a gift to give yourself for $200!
I guess I've got to buy myself some fancy fuses because I can't tell what everyone looks like on my recordings. Or not.
But....audiophile caveat.....I'd "have to hear it to understand."
If only I'd just "trust my ears".
The resolution is so high that you can discern the nano reflections of sound off the microphone's grill, which bounces back to the performer's face, mapping their facial expressions, which then is picked up by the microphone again. Kind of like a Sonar for vocalists.How on earth can changing a fuse allow for anyone to discern the personality and facial expressions of the performers on a recording?
