If you go to the Purist website and download the PDF catalog which includes all specifications for each cable they make, you will see that all of their interconnects use a silver/gold alloy + copper in all their ICs -- even the least expensive models. No pure silver or silver-clad copper is used, which can sometimes cause the brightness or high frequency grain often attributed to silver.
Alloys also have another advantage. They are much less sucseptable to corrosion/oxidation at the conductor/dielectric interface.
Only a handful of manufacturers use proprietary alloys for their conductors. Magnan (bronze,) Purist, Van den Hul (I think) Siltech (I think) and maybe a couple of others. In any case, this represents a high material cost to the manufacturer since it is a custom material produced in (relatively) small quantity.
I use all Purist, and if you look at my system components, you might think it would sound bright or analytical, but it doesn't.
