I’m trying to make my own balanced cable for my Meze 99 Noir and have some trouble with the wiring, I was hoping someone here could help me. I have a 4.4mm Pentaconn connector that connects to the amp and two 3.5mm TS connectors connecting to the headphone. If my understanding of how a balanced cable works is correct, it should work if I wire the positive and negative signal to separate parts of the 3.5mm connector, L+ to the tip and L- to the sleeve. If I connect the wires as shown in the picture below would this be correct?
Can hook up ground on the output side and leave floating (= unconnected) on headphone side, or tie to the plug housing (assuming the headphone side plug(s) have a housing for that) so the headphone itself is grounded.
DO NOT tie the ground to any signal! Neither plus nor minus!
