Hi.

Since Hull's carbon fibre IC cords have been in the marketplace for over a decade, how come they are still not so popular to replace copper or pure silver cords considering Hull's LSC ('linear structured cystal) technololgy being reportedly superior to metal conductors, eliminating CCD (cross crystal distortion) etc etc?

One huge downside of graphite (carbon) is its inherent high resistivity. (typcially over 800 times of copper). That's why finely powered carbon has been used as electrical resistors for a century.

To used carbon or graphite fibres as audio signal conductors, hundreds of thousands or millions fibres have to be bundled up to get the low low resistance of copper.

Being a bad shielding material to strong electrical mangetic fields, Hull recommends not to put its carbon fibre ICs close to power transformers in tube amps as its shield resistance is high typically up to 14R/m vs only 0.01R of copper.

Hence its new First Ultimate get a heavy metal shield on it.

Anyway, hearing is believing. Do carbon fibre ICs sound good as Hull claims so?
