Take a look at what BJC does with their speaker cables. Of course Blue Jeans Cable has zero cache and no heirloom boxes.

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.
