hi gentlemen,
I would like to build my own analogue interconnect and loudspeaker cables made with carbon. I just don't know where to get carbon material which suitable (flexibility, conductivity, etc) for cable assembly? has anybody made something like that?
any help appreciated!
best regards

Well graphite along its planes is only 150 times worse than copper, might work for signal level, but not sure its flexible enough.
Nanotubes might fare better, I don't know if that's practical, but long ones have been grown experimentally: Growth of Half-Meter Long Carbon Nanotubes Based on Schulz–Flory Distribution Whether that's affordable and can be connected reliably I don't know, but the basic physics suggests it could work.

This subject reminds me of the old carbon microphones in telephone booths. Crackle ... hit the phone and ... it rearranges the carbon for a short while.
Not a good idea for cables and very unreliable.

Clearly amorphous carbon is useless for this, but graphite and its relatives have delocalized electrons and would be the way to go if its at all feasible.

Traditional automobile spark wires were a loose linen thread dragged in powdered carbon and then rubberized. The high resistance damped some radio interference.
We usually assumed 1,000 Ohms per foot. You may want <1r/10'. So it has to be 100X the diameter. About 10 inch diameter linen "yarn".
Aquadag is another Carbon "conductor".

There must be a reason conductors are made out of copper and resistors out of carbon, don´t you think?
Sorry your first post is not going so well, stahlhelm!
There are many allotropes of carbon, one being diamond if you're feeling flush!

Carbon is resistive. You don't want that.
Go for Platin, Silver or Gold, or if You have a lab nearby, try superconductors.

the reason: I heard a carbon/graphite (I don't know exactly what material it was made form) speaker cables and it blew my mind. it was absolutely fantastic and the best so far I heard. I want to build something like that because it is very expensive. I want to experiment with carbon/graphite DIY cables.
1) placebo effect.
NO WAY a wonder cable can make your amp "sound better" than same length of good old copper cable. NO WAY.
Even less in the superlative tones you use to describe it, so you are clearly "listening with your wallet"
There is a reason cable threads end in chaos and are closed down.
The ad brochure for the cable you mention must certainly "mention" carbon graphite or any other wonder material, be certain that if it worked at all (meaning it successfully connects an amplifier to a speaker) then it has copper inside, or maybe Aluminum.
Even Silver if you feel fancy.
MAYBE the insulation contains such materials, that does not affect the sound.
By the same token we talk about a Teflon cable, PVC cable, cloth and rubber cable, etc.
In all cases we are talking the insulation, not the conductor.
A series resistance, pushing the operating mode to more current mode than voltage mode can be shown to change FR and in some cases reduce distortion. But a good cable and a series resistor will do the same.
Yes, I'd also guess that the cables the OP has been looking at just had woven carbon fibres as their outer sleeve. That's the same mojo why others love to tag carbon fairings to their rides.

Carbon strand interconnects have been around for a very long time, nothing exotic about those. At some stage i also had a pair and although not truly horrible they didn't stick around for long. They also had substantial resistance but whether it was 10 or a 100ohm i no longer remember.
Cannot imagine carbon wire being of sufficiently low resistance as to be usable for bass driver duties. Tweeters and midranges are usually resistor padded, so there it may shine as a combined cable/risistor. Especially if one likes the carbon sound.

Hmm, a brand new forum member first posts start drifting off into praising a commercial cable.....
The reason carbon worked in HT leads is that the kilovolts could blast through any momentary bad connection and nobody cared if the spark current was slightly AM modulated by engine vibration
