Just as important is what they connect to. You know the plastic part it connects to inside whatever device you are connecting to. Same concept when monster cables were a thing, the gold plated connectors that connect to the back of your tv using plastic and undefined metal.

I like to head on over the auto zone, get me some of that dialectic grease and dip all my dac cable ends. Just feels good going on ya know?

Edit: onlyfans? Like just me greasing up different terminations and inserting them.
