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?

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.  
Sure, of course, wire is directional.  The sound is really a lot different if you accidentally install them in the wrong direction.  
Uh, I hate to be the one to break it to you but just because a cable has arrows 🔚 it doesn’t mean they were controlled for directionality. Follow? I’m pretty sure the dude from Monster Cable never got on board the wire directionality train. The train left the station without him. 🚂 toot! toot!
