Directionality Explained

Not specifically me, but it would be people who have a clue what an experiment that involves subjective human response looks like, and any time you have to measure subjective human perceptive response, you have to isolate what is being tested, which means using only your ears, and not your eyes. Test as long as you want, test with whatever music you care to test with, get 20 of your audiophile buddies together, ... you just don't get any visual clues about what is happening. This is not rocket science.

Oh and while you're at it, just who gets to decide "what would pass for" scientific evidence?

Would it by any chance be you?

To heaudio123,

You have been saying our hearing is so poor based on scientific evidence, would you mind sharing those "scientific evidences"?

Most bulk circuit effects, i.e. resistance, inductance, capacitance are not even at the level to be audible (unless poorly designed/specified).

Apparently, our hearing can be effective if the cable is "poorly designed".  Based on your logic, all good cables
should sound the same since we cannot hear any differences.

The next question to ask is what constitute a "good cable"?  Who gets to decide?  There is a flaw in this logic.

Also I don’t buy the fact that the "resistance" is lower in one direction vs. the other as said here by Mr. Kaitt.

For example, each spool of wire consists of many many meters of wire. If the wire always measure less resistance in one direction, then by the time you measure from the beginning to the end of the spool, the resistance may go smaller and smaller into "negative". So this can’t explain it either.

>>>>My nomination for the most absurd explanation for why directionality cannot be real. Are you posting while high? You little dickens come up with the most ridiculous reasons why something isn’t possible. Perhaps you’d be better off coming up with reasons why it is possible. 

I hate to judge before all the facts are in but haven’t you skeptics jumped to conclusions? You know, you’re suppose to test BEFORE 🔙 drawing conclusions, not AFTER 🔜. Hel-loo! All this chitter chatter about blind tests or any kind of tests for that matter is just talk. And talk is cheap. Do your own tests and report back. We’ll see who gets what results and tally them up. Gee, it’s almost like you guys never heard of the scientific method. You start with a hypothesis and test to see if your hypothesis is true or not. It’s not complicated. Come on, guys. Get it together.

If the impact on frequency response is <0.1db there is little(no) evidence we can detect a difference and even more variance at the upper end of the spectrum to detect a difference. Now try to find a cable not inherently directional, i.e. with circuitry that has 0.1db difference in the audio spectrum by changing direction. Feel free to use square waves for tests with bandwidth limiting and real speakers for transmission line effects.
