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 know the electrons carry the charge (EF) across an electrical potential through the circuit at near TSOL.  Electrons do get exchanged very slowly as well, but I see your point.  As Spock would say, it’s Pure Energy!
The constantly changing frequency of the field tracks the musical program material?  That’s all I got 😔
Can we agree it’s the rate that current and voltage alternate? If so, then what cables and wires carry is plain old current and voltage.
