Soldering cable ends for AC terminations

Solder adds impurities, No solder is best.

mapleleafs3, and where do those impurities go? And aren't they 'flushed out' by the current after some time?
At any rate, I don't see where it makes a difference if the solder is just at the protuding end of the connection where there is no current.

Name me an electronic component out there that is not full of it! Solder that is.....
Solder is the electrical bonding agent that holds all the electrical connections together. Printed circuit boards could not exist without the use of solder to electrically connect electrical components to them.

Where solder can cause a problem is where it is used for tinning the ends of speaker cables and such. Solder does have a tendency to corrode on the outside where exposed to air and moisture. Beneath the surfice of the solder this is not a problem.

Jea48...I have no problem with solder in audio equipment, but there is electronic equipment that uses another method which sounds unlikely but actually works very well. I am thinking of "wire wrap". The soft copper wire is twisted around a hard sharp-cornered pin, while under tension using a special tool. This method was used for thousands of connections in the electronics assembly of a missile inertial guidance system that I worked on. Very reliable, even under extreme vibration during missile flight, and unaffected by nearby nuclear explosions, where solder would be melted by X-rays.
