How do the silver cables improve the sound?
In theory, you should get a faster signal transfer and less coloured sound. In reality, it doesn't. xD
I also am not a big "believer" in significant sound difference between cables. However I can't really comment on this because I never actually listened to the headphones with the stock cable (which is also silver). I bought the headphones 2nd hand and the previous owner re-terminated the stock cable with a balanced connector. Because I don't have a balanced system I bought 2 different (aftermarket) cables from someone else.
Both of those cables sound very good, however I do get a bit of microphonics with them, which is why I ordered a much more robust, well-isolated cable (from Norne Audio). So once that cable gets here I'll really have too many cables, so one of the silver cables can go to a new home...
