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?

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......
Geoff, ever since you mentioned you live in DC, your directionality thingy kind of lost its mojo for us country boys.
