Siltech G7 Silver-Gold alloy

Many cable brands make extravagant claims about the purity of their conductor material, often citing impressive sounding terms like “six-nines copper” to justify them. This misrepresents the problem – the issue isn’t how many “nines” you can get but what the remaining “one” represents. In other words, that last 0.0001% is more important than the 99.9999%.

the gold atoms naturally displace contaminant particles and fill any voids in the silver crystal matrix

That contaminant has a profound effect on the musical performance of the conductors. Quite large amounts of some materials can be quite benign, while even tiny amounts of others can be extremely intrusive.

At Siltech we learnt early on that the specific identity of any alien matter in our conductors was of vital concern, leading us to develop our revolutionary Silver-Gold alloy. This mixes a tiny amount of gold with the silver; the gold atoms naturally displace contaminant particles and fill any voids in the silver crystal matrix.

The result is a greater material consistency and dramatically reduced contamination, significantly improving both the performance and longevity of our conductors.

Although we first developed Silver-Gold alloys nearly thirty years ago, we have continued to evolve and further improve them. These continuous improvements have led to perfecting the technology further, now reaching the seventh generation, G7.

They continue to offer superior performance to competing conductors and we still employ them for all our Classic Anniversary and most Royal Signature products today.

However, our continual research programme has enabled us to develop even better formulations using silver alone – our monocrystal and infinite-crystal silver. To learn more, see the metallurgy S8 Monocrystal Silver section.
