Siltech Technology: When Silver Meets Gold.
To understand why Siltech uses silver and gold metallurgy for its cables, we need to take a look at silver’s crystalline structure. The natural crystal structure of copper and silver does not exhibit the characteristics of optimum conductivity. It produces small distortions when current flows through it.
The crystal-group boundary affects the signal which generates these distortions. These crystal-groups can be seen as ball-shaped clusters of crystals. This clearly provides less material for conducting, and a more complex signal path with air gaps in between. Siltech has developed a proprietary technique that greatly reduces these crystal boundaries.
After purifying the silver (between melt and solidification), Siltech adds 24K gold to it. The gold fills the empty spaces between the crystals and improves the mechanical and electrical signal transmission properties. This lowers the distortions dramatically, improving the signal to noise ratio. The result is far superior audio quality.
