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.
