All cables have two conductors!
RCA cables are coaxial cables, meaning that each cable has a positive conductor (inner) and a negative conductor (outer).
What's better, one conductor or two conductors for an RCA interconnect?
I have a somewhat nice RCA analogue interconnect with one conductor, referred to as a coaxial Cable I guess. But I see higher end RCA cables with two conductors and ground wire. Which is better?
Is better detail provided when connections are made with two conductors?
