Soldered VS ...everything else

A few thoughts:
As alluded to above solder comes in many alloy formulations.
The good old wire looped into a screw down terminal alleviates one connection point.
Silver and silver oxides conduct better than gold.
As to what everyone prefers...

I'm not proffessing expertise in welding specification, but it would seem to me that the usual crimp connection afforded by audio terminations is not a true cold weld (vacuum, pressure, etc.)
At any rate once a connector is attached it still goes through another pressure fit connection of some 'modest' pressure.
As an aside looking at construction techniques employed in vintage analog test equipment (tektronix etc.) is fun.
