Sterling Silver is all over eBay as well from Chinese retailers. I'll let my ears judge if indeed hear some sonic benefits from the cables. I didn't think OCC copper would provide enhancements but for some reason it's apparent when I switched from Mogami interconnects to Neotech NEI-3002. Then going up to NEI-3001 was yet another improvement that was immediately apparent.
I'm in the camp that I should hear sonic benefits immediately, and if that's not the case then it's not a good buy for me and it's returned.
I'm excited for the potential of these new cables and will report back with real insight.
