Crystal uses a unique silver and gold combination which helps deliver better sound and signals.
The very pure silver Crystal uses has a crystal structure. That means by solidification of the metal, you get round-shaped crystal boundaries touching each other, buy having "bad places" where they don't touch.
These bad gaps are filled/injected with gold, which is the only metal that can be used for this.
It makes the way of the electric signal smooth and in time again.
Sorry, but... I don't know what to say, I'm at a loss for words. I'm just gonna go sit in the corner with my magic stones and give this some thought.
