To those of you who were in favor of silver, I can highly recommend AN-Vx cable. This is an interconnect cable and has to be terminated properly. You can buy the cable from Audio Note dealers in the US, like Amherst Audio (MA), Audio Federation (CO) and Deja Vu (DC), among others. It's the best interconnect I have found so far (except for higher priced AN cable) for any of my equipment connections or headphones (the second best being Audio Note Lexus, a copper cable). They are pricey, though.
