I don't own Coppertones but I have a full loom of Black Cat copper cables in both systems:
Redlevel Coeur speaker cables
The Tube! interconnects
3202 interconnects
3232 speaker cables
I don't see any of these models any more in the lineup since Chris has relocated back to the USA, but they are all copper. If I had to start over again I would go with Coppertone. I also use one his old Stereolab Master Reference digital cables.
I don't think about cables any more since I bought them. If Chris made a power cable I'd probably buy that too.
