Yes, Timrhu is correct, and this is audible!
Expensive cables/connector and solder
Why there is so much intest about buying expensive cables/connector made of exotic materials if the end wires are thinned? I understand that the solder used in most applications is 60-40 lead-tin or so. Then is the conductivity of the solder as good as the copper or whatever exotic material is used to make the cable/connector?
