geoffkait, you asked if anyone new about "hookup wire" that had Graphene in it. Well besides the Synergistic ones below is links to another company.

I have not heard their cables so I can not say how well the perform.
But Graphene and its potential in many different uses is very interesting, let alone its potential in Audio.
PS I remember reading a respected Audio designer was developing cables made out of Graphene (I believe they were close to pure Graphene). This was a report from one of the shows in Europe about two years ago.
