"According to the manufacturer, the metallurgical processes were optimized in the course of the revision to the new "silver-gold", SG2 for short, which increases the cable quality. And even after production, the gold migrates to exactly the right places in the silver, so that the performance of the cables continues to increase over time, instead of decreasing due to aging, for example. I can confirm this self-confident statement on the basis of observations during the test at that time and especially over the span of time that I have been using a CrystalCable in my system. Because this is indeed getting better and better!"
