No one actually knows how to lculate what speaker cable they need

It goes back to cable manufaturars, mostly provide no relevant data! to sales and the users. None will answer this!
Whay do you think that you own now the optimal cable to your setup?
I think I've figured it out. 

Mr.  eichlerera
Sorry to disappoint you, but I don't have a theory of MY OWN, on electrons flow through the conductor. I learned it as all other from the very basics on conductivity. 
It served me well, on all circuitry I designed, built and tested. 
This reads like kenjit created a new on-line persona to bring his unique perspective on speakers to speaker cables. Clever. What next? Amplifiers? DACs? So many targets for a guy with an obsession to feed and no discernible listening skills, leaving only one way it can go. Blather on, dude. Blather on.
Sorry, I have no idea of what you are talking about. You must be mistaken me with someone else. 
Can we please get back to the subject? Thanks.

Just saying, I've been vaccinated yesterday for COVID-19. Here in Israel,  vaccination is the fastest progressing in the world. Now in 30 days I'll be safe and immuned. 
So' I'm good with COVID-19, but still need to fight for my identity with you guys?
What a world...
Mr. Dill, did it ever accured to you that it worth giving my idea a try?
