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?

So, we’ve got some smart dudes here with differing opinions. I think that’s really cool because that’s how I learn. Now I want to open up a new can of worms that I’m really intrigued about but don’t have an informed opinion. Is there any advantage to solid core wire as opposed to stranded? I’ve seen seemingly valid arguments on both sides, but I haven’t seen anything definitive one way or the other. What say you?
Not to beat a dead horse, but I have had recent experience with solid core cables as well. I know experience doesn’t matter but...what the heck! Solid core (Anticables Reference séries and Audioquest Water) offer some wonderful properties. Clarity, reduced distortion, speed and impact (rhythm, pace and dynamics). System dependency will either put these in the must have category or in the too much detail camp. Comparatively, the Transparent cables embué the sound with more solidity, dynamic contrast, extremely low noise floor, a rounded well fleshed out midrange, pure natural highs and bass that is extremely physical.
Interestingly those two examples - Anti Cables and Audioquest Water - are both prime examples of cables that are controlled for directionality during manufacture. Thus, I would caution that their sonic superiority might well be due to their correct directionality, not the fact they’re solid core.
