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?

Quad 57s can be rather pedestrian 🚶‍♂️sounding in certain respects unless they are placed on stands, the heavy rattle-trap metal grills are removed and the plastic dust covers are removed. Oh, and replace the power cords and remove the entire electronics package and put it on springs.  Much more open, resolved, extended and dynamic with much better low end.
Yes, I agree completely!  We have achieved agreement...see, and they said it was impossible 🙃
A shame you can’t change brains, glubby. I suspect somebody pulled the old switcheroo on you. Hey, that rhymes!
