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?

Don’t be a negative Nellie with silver. it depends on where in the system it's used, the purity.,gauge ,how long the break in period is, and whether it's been cryogenically treated. In fact two cryo treatments are preferred for silver. so, yes, sometimes silver is superior to coper, especially in transparency, dynamics, resolution.
