So you think wire conductors in cables are directional? Think again...


Here is a very relevant discussion among physicists about the directionality...the way signal and electrons should flow... based on conductor orientation. Some esoteric, high-end manufacturers say they listen to each conductor to see which way the signal should flow for the best audio quality.

Read this discussion. Will it make you rethink what you’re being told and sold?

Since when does success in any educational system equate to intelligence or overall ability?

Was a time when the U.S. was good at teaching kids how to think. Now instead of facts we have opinion and social indoctrination. Public schools of course, cant speak to private.

They are the very easiest to fool because they rely on what a meter or computer tells them ad in fact they are expert at fooling themselves as is evidenced clearly, plainly, and abundantly  by they're posts on this site. 
Look at all that chest puffing, but not an argument among the four of you. That is rather telling.
If current day scientific knowledge explains everything about sound reproduction, why do the self professed "engineers" have the very worst sounding systems? 

By 1945, our knowledge was doubling every 25 years. Today it's estimated to be doubling at around 18 months or less. If there is anything that we can be totally assured of, is that each and every so called scientific law know to man, will be proven false or woefully inadequate some time in the future. 

If you trust a measurement over your own ears, you are not terribly smart.

Note. I have not personally heard a difference in direction of a cable, but I have no reason to doubt those who claim they have. Science most certainly does not prove them wrong.
