I used to manufacture cable ...sold it in NY, NJ, etc. I always found that soldering degrades the sound.
Cardas Cold Forging
Has anyone tried the new Cardas option to have their speaker cable and connectors cold forged, making for a solid connection with no "connective" points with solder, etc. Sounds good in theory for line transmission, but can you hear any difference? If so what? I'm using Cardas Golden Reference.
