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.

Al, well said. Hard to know what to do since I'm skeptical I could hear the difference, but that doesn't mean I wouldn't and to the better. Like I said before, I do wonder why this approach wasn't done long before, since the ability to do this has been available for years.
You can see here Cardas Two Stage Compression Die Forging that the process results in a metallurgical, homologous material with any gaps. These gaps can act as capacitors, two conductors separated by a dielectric, in this case air, which can cause changes in current flow and frequency response.
Lenny, I had looked at all of that before posting. And the question would be HOW MUCH is the capacitance you are referring to? I doubt that it is much more than 1 or 2 pf. Compare that to the overall capacitance of the speaker cable itself, which is probably hundreds of pf's for typical lengths and typical cables, and then consider that even those hundreds of pf's represent a completely negligible and unimportant impedance at audible frequencies, in relation to both amplifier output impedance and speaker input impedance.

If the forging process makes an audible difference, it is not because of the capacitance you are referring to.

With all due respect, IMO qualitative theories that are not put into meaningful quantitative perspective are a pervasive problem in audio.

The engineers I used to work with said that the purposes of both solder and crimping are :

1)Mechanical connection

2)Exclusion of Oxygen, to prevent corrosion

They preferred crimping over soldering as more consistent and reliable.
