Cardas Cold Forging

This is a pretty cool process. Here is another article;

to everyone, the cost for cold forging a pair of single run speaker cables is $300 or $37.50 a connection (this is for 8 spades). the cost for cold forging a pair of internal bi-wire cables is $400 or $33.33 a connection (this is for 12 spades). the connectors used in this termination are unique to this process. the wire is litz so the coating has to be removed. a chemical is added to the connection to keep out impurities. the whole process is very labor intensive. what you are left with is a connection that is a solid piece without solder. it is much more than a crimp because the copper actually melts and becomes a solid with the connector. it took mr. cardas two years to develope and test this process. it was first avalable in the cardas clear cable. cardas is now offering this type of termination for all of their speaker cables and from what i have heard, people that have had this done end up with a profound improvement in their sound.
first hand knowledge always beats speculation.

Thank you Bobby, you addressed my question from 4/2 about whether the enamel is removed. Can you add any more details about how they remove it prior to the cold forge process? I suspect that is not easy in the absence of tinning the wire.

mitch,
Day one: Old terminations removed. Ends are dipped in solvent to remove the clear coat on every strand.
Day two: dipped again, while being agitated. Set out to dry
Day three: unwind the conductors using a couple of wire wheel hand tools to remove remaining residue from stripping process. Two stage crimping process, resulting in each strand being fused into a solid lump, and then fused onto spades.
this is the description from turboglo above.
ok mich?
best, bobby

Geez Bobby, sorry but I totally missed tuboglo's post. I am on board with the process since I use high pressure hydraulic crimpers on the cables I make; using a similar die, two crimps and trim the spades, very similar to the Cardas video, but of course not the same pressure or degree of fusion. I much prefer that crimped connection to soldered connections I have done, but I haven't tried it on litz wire. I am glad to hear those who have had cold forging done to their Cardas cables prefer the sound, although I would expect nothing less from Cardas.
