Riddle me this: how is carbon a conductor?


I'm confused....

M. Wolff has a powercords, and now interconnect cables, made with "carbon ribbon". But when I look up the conductivity of carbon, it's a thousandth of silver's. Almost the same delta for copper.

So why use this stuff in the signal path?

It makes no sense to me (other than he also uses silver) that this is a good design call. Is not what one hears with these designs the non-carbon conductor geometry rather than carbon ribbon?

Really, this is not a shot across your bow, Michael (or to any who is satisfied with the product), but an attempt to understand why use such a poor conductor in the signal path?

Curious, 'cause I'm in the market for IC's and power cords, and attempting to understand the product offerings.

Thanks,

Our IC's are not limited with regard to high resistance than what is normally expected from any IC cable manufacturer.
TBG: Not applicable with the Empress. One customer ordered a 4 meter pair of XLR's

Best,

Trelja made a very good point when he said
"So, after this way too long babble I have put forth, carbon is, FOR SURE, a conductor. It's not as good a conductor as silver or copper, but it is still a conductor. Whether I would use it as a power cord or not, is irrelevant to this argument."

We not only understand that carbon or graphite is of a higher resistance than thier metal cousins. Who says resistance is a bad thing. We certainly experience a lot of it right on this forum.(Joke)
Anyway, there are some characteristics that carbon has which make it a preferable medium to use. For instance, copper exibits frequency group delay in frequencies above 10K Hz. Carbon on the other hand is flat as a board up to 100K Hz. ten times that much. If you read about the super tweeters that are out they advertise frequencies in the 100K range. Can we hear 100K. Of course not. However, we can not hear 20 or 25 Hz. either, but yet it impacts the music as a whole. So the super tweeter manufacturer's are touting the same benifits at the highest frequencies. There is a review on Positive Feedback about such a tweeter.

Another person that has seen some benefits in using carbon is Steve McCormack. You can read about his carbon and siltech upgrades to his older amps at http://www.smcaudio.com/ .

The interconnects and speaker cables are a co-design between myself and a gentleman named Grover Huffman.

And by the way, Sean "I guess that we will never know as the people writing their ad text are not technically competent and / or they don't display any pertinent info to the subjects being discussed on their website."
I always love to see your ASSumptions.

Excessive stress and movement in any power cord or wire device would eventually cause a fatigue condition and which would lead to a mechanical failure. If the transmission of either AC power or a signal of any kind is dependent on the
the ability of the compound to share electrons, it would indeed cause either a degradation or failure.
We recommend just as any power cord manufacturer not to use your power cords (especially the expensive ones) as bolo whips since thrashing them around over your head does indeed shorten their life expectancy and could lead to tennis elbow.
