I've seen pictures of the inside of the cups, so I know about the 3 (impossibly thin) wires connecting to the left cup, which I'm sure I could replace with small segments of whatever wire I choose to use (I will have to replace the wires to the right cup if I choose to use silver (if anyone has done this, how does silver wire affect the sound on the 770s?)).
Part 1 of my question:
One of these wires is left and one is shield (ground?). The other (center wire) is right?
Assuming I'm not going to prepare these for balanced output (should I? Is there a benefit?), does it matter which pin I solder what wire to? Assuming, of course, that I repeat the same wiring scheme on the other (female) connector?
