directional cables?

This was not easy to read, or to follow at many times. The entire time I kept trying to decipher the truth, the facts and the science, and that, I admit took an effort to open my mind, question what was being conveyed and argued, and argued, and argued... However, I believe that I finally reached a conclusion, that required understanding different abstract (?) concepts, or at least  concepts that were originally foreign and misunderstood. Grasping abstract concepts that challenge one’s simplistic, preconceived thinking has required considerable open mindedness, and effort. 
I’d like to thank Herman for his perseverance and his tenacity in illustrating what I have come to understand are new ways of understanding electrical concepts.

A very tangible result in this experience is that it has now,  believe it or not, allowed me to make up my mind about which interconnect cables and speaker cables to purchase. That is because this entire experience, (this brutally difficult to read thread) has tied in so meaningfully to the philosophy of one (or 2) audio component (more than just cable) manufactures that I have been investigating, which I now understand, understands these concepts and the science. (Coincident Speaker Technology, since someone may have wondered who that is.)
Thank you, Herman! This has been tremendously informative and valuable!

Even though this is mostly a ten year old thread it is interesting to read parts of it if only to see how much some people keep repeating what others have said, quoting them and providing links to other threads by the same folks, not to mention repeating themselves ad infinitum. The other interesting thing, for me anyway, is how everyone scrupulously avoids the question of directionality contained in the OP. And no evidence or theories one way 🔚 or the other 🔜 The more things change the more they stay the same.

There is evidence in the form of directional crystal structures, as well as the fact many are able to hear a difference. Either way, evidence.

As for theories, there are theories galore.

Even though most ten year olds could understand that much, it apparently is beyond the realm of theoretical physics and interstellar propulsion engineering.
