Interconnect Directionality

jea48, do both you and GK both go to the pedantic school of engineering ignorance?  CONTEXT. Quote EXACTLY what I wrote:

3) Current IS the movement of electrons literally by definition. Current is measured in Coulombs / second AND SINCE POSITIVE CHARGE CARRIERS DO NOT MOVE, THAT MEANS ELECTRON MOVEMENT.

It is pretty obvious, if you are skilled in the art, from the above I know that a) Coulomb, is a measure of charge. b) That coulombs/second is a movement of charge carriers, and c) that charge carriers can be either positive or negative (electrons). I ALSO know that in a wire there are not mobile positive charge carriers, and HENCE, in the context of the post, which was about whether current in the wire was the flow of electrons (and not photons), that by definition, in that context, CURRENT IS THE MOVEMENT OF ELECTRONS.

Now, if you wanted to say, "Hey, I get what you mean in the context of what you posted, and it is clear you understand current is the flow of positive and negative charge carriers, but others may not understand the context, so probably should not say "by definition .... "  then perhaps you would have added something to the conversation. 

OK, this conversation has officially bottomed out. 🔚 Let’s hear a little from the professionals on the dodgy subject of is there or is there not directionality 🔛 in wire. You have to ask yourself, why would somebody go to all the trouble, and expense, of controlling directionality for speaker cables, interconnects power cords, HDMI cables, Ethernet cables? Does anyone really believe they’re running a scam? Is this some foul hoax perpetrated on naive gullible audiophiles to squeeze them dry of their hard earned cash? That doesn’t make any sense. If it doesn’t make sense it’s not true. Come on, people! Hel-loo! Deprogrammers are standing by.

Exhibit 1 - AudioQuest on directionality

https://www.audioquest.com/theory-education/article/83-directionality-its-all-about-noise

THE ACTUAL PROFESSIONALS .... you know, the ones that make 100GHz cables, that ones that put gigabits through twisted pairs, the ones that developed the HDMI standard, the people who make measurements systems, all the ones where real bits, real SNR, real waveform shape = money, the ones whose customers have sophisticated test and measurement equipment, etc. etc. would never ever claim, except where a directional shield is concerned, or there is an intentional passive element built a cable, that, within the framework of audio, that directionality of an interconnect has any detectable difference in the sound. 

The AudioQuest article is meant to SELL cables to people that cannot read what they have written and say "BS - this does not apply at audio frequencies, and this does not apply well, almost ever". You can't say in one sentence, oh, our cables are amazing, due to their fantastic shielding, and then claim a paragraph later ... well ya know, there is directional impedance (is there? ... how much), and ya know, that RF interference will cause things to ring yada yada ... well which is it? Do they shield from noise, or do they cause some strange effect that no one outside the audio "marketing industry" has ever experienced? .... OH, and lets not forget, all signals in audio are AC, AND at analog audio frequencies transmission line effects don't exist and any that would would be swamped by source impedance, load impedance, and cable mismatch ... of which we can guarantee there are.  If it is USB, Ethernet, etc., unless it causes data loss, and it won't and it is easily tested with a BERT, it is meaningless. What is the typical USB / wired ethernet data loss in the home? ... effectively 0 for audio, i.e. you may lose bits every once in a while, not at any rate that would impact audio quality.  Want to throw timing at me for a electrical SPDIF or similar? .... easily, easily proven, lots of excellent test equipment out there that can measure jitter at the receiver, equipment that actual technical professionals, not marketing professionals use. Easy for any of these company to measure a jitter improvement claim, you know like was done to show the improvements in electrical over optical connections. Of course lets not forget that any competent DAC today buffers and reclocks so that jitter on the input has no correlation to jitter on the DAC.

>>>>That’s what makes the whole directionality thing so interesting - that it IS audible. It’s as plain as the nose on your face. All wire is directional. Simple tests can be performed by any REAL skeptic, someone who was interested in getting to the bottom of things rather than a pseudo skeptic who prefers debating endlessly. 🔛 All you need is an open mind, and a little curiosity, you know, parts of the scientific method sometimes conveniently forgotten. Follow the arrows. 🔚
