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?

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!
And all the photons, neutrons, and protons get all turned around.  Little amy is likely liable to forget her lunch money, and johnny his gym clothes. 

Oh man, what a mess.
I was shocked nobody jumped on that line like the hot potato it was GK.

I just could Not rpt Not leave you hanging buddy......
