Who has the technology to apply a single-molecule layer of carbon--a semi-conductor manufacturer? Would an audio cable or fuse even benefit from such a thin layer? Doubtful, but some process or material is providing superior conduction in products I am using, including Total Contact and SR Blue fuses--this much I know.
Beware of new material claims - the case of graphene
Given that graphene is quite the in vogue material for audio applications I wonder how many (if any) of the vendors selling this are actually sourcing the real thing?
