Speaker wire... Diy?


I am new to this, so please bare with me. I always thought 12 gauge speaker wire, bare on each end, was best. But there is Kimber, Nord, etc, that seem to be incrementally better! Can I buy the components and put together my own $17000 speaker wires? If so, where can they be purchased, and which are good enough to be used? Which terminations are best for sound? Which wire? Length? Guage?

I’m full of them.
  I REALLY had to bite my tongue there...…..

Kimber cable at $10? Would be shocked if it was genuine, no offense.....

GK has a bit of a point, of course many of the cables I’ve used are directional.

But not any of the stranded ones, yes?
It looks like I got a bite on that “I’m full of them” line. They’re bitin’ today! 
My MIT’s and Transparent cables are directional...even some old M series Monster cables I have are directional.
