Graphene infused OCC conductor

There is also the question of increased conductivity being always desirable. Silver is more conductive than copper. Does that mean silver cables are always the best choice? No

Zavfino silver darts use the graphene as the dielectric though, not a "graphite infused" conductor. 

What is Zavfino ZGRAPh-LDP GRAPHENE ?
Zavfino is the first audiophile cable OEM to integrate graphene insulation into high-end A/C power cables as a dielectric shield. After more than two years in development with a leading American graphene polymer research company, we’re proud to unveil our new proprietary ZGRAPh-LDPTM conductive shielding/dielectric, first used within our Silver DartTM OCC A/C power cable.

1877Phono or Zavfino are a legit company who do their own manufacturing, and manufacture for other cable companies as well. Tons of information for you objectivists who read more than you listen, and that picture of the construction should/might make you froth at the mouth, but because you will never find any graphs "showing" you they have measurements better than your Belden/Mogami’s, or because you will find something to argue with in their marketing you won’t try them. Shame. 

Most importantly, I own 3 of these Silver Dart power cables, and they do make what they are plugged into sound fantastic. Is this the best $1000 US power cord you can buy for the money? No idea. Be warned, they are a real b***ch to work with though, many would not use them for this reason alone.

I am based in Europe

Just noticed this at the bottom of their page, and last I heard, like many other North American based audio companies, Zavfino sell more in Europe and Asian markets than North America. 

My curiosity is peaked.  I will try some copper-graphene cables in one of my audio systems.  My ears will be the judge not a bunch of theoretical explanations of why it makes no difference.  If it does not sound good, the resolution in my systems will shine a flood light on its bad sonics...
