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

kalali,

"BS flows downhill thus directionality exists."

I think that plumbers are underappreciated and underpaid. As you pointed out in some way, they know a lot about directionality and narrow points in the flow. Like going from 0 AWG to 8 AWG at the end of the cable. It is still quite a mystery to me why, in this thread, large diameter is a crucial positive influence while narrowing it at the end is negligible.

Mr. geoffkait

Directionality can explain nothing. There is nothing in electrical science to explain such a thing in cables. It exists only in audiophiles minds that were talked into it at the time they were set up by the industry, with that excuse. So is the BI (Burn In), metal purity and all that long and annoying list of urban myths.

You better look for the explanation somewhere else. I can give you a hint, but this thread is all about it. Your attitude to accept the truth (especially of the six testimonies of the guys who tried the DIY cables, I offered), is in a denial. I have a bad feeling that no matter how many will say the same, you will stick to directionality.

Just let me say it again: there is no such a thing as directionality, and with something that doesn't exist, nothing can be explained.

 

What we have here is failure to communicate. This whole “misunderstanding” regarding advanced audio concepts like directionality, burn in and purity of metals can probably best be explained by quantum physics. You see, think of me as an electron in a higher energy shell and you’re a lower energy electric orbiting in a lower energy electron shell. It takes too much energy for you to get to the higher energy electron shell, up where I am.
