speaker cable prices

From what I've read, it's the signal that goes to the speaker that matters, so go for the direction that best facilitates that, no matter how small the discrepancy.

As for what can possibly make a cable, any cable, directional? It seems to be that all cable are drawn through a die, and that impresses the structure enough to give directionality.

Back around 1990, I had a local cable builder make a set of speaker cables for me. He had a workshop out back of his house, and in it, were every connector made and sold (at the time) and looms of wire of varying gauge.

He simply laid out one cable, measured it, and then reversed the cable and measured it again. He did the same for the next leg and laid them so that they both measured similarly, in the same direction.

He then sleeved them and attached the connectors and the whole process was repeated again. He then applied the heat shrink and marked directionality on the cables.

He told me he was just making sure they oriented in the right direction.
He measured, and read, enough of a difference to justify what he did. I never gave it a second thought until I joined A'gon.

I paid a little over $400 for the length I needed and it was solid, silver core. If you don't need 14 gauge and something like 16 gauge would suffice, then check out Tempo Electric : Pure Silver Cables.

They don't have the bling, but boy, do they sing. 🎼
