Kimber D60 Digital Cable?

One thing I notice is that in the latest version from Kimber, the dual layer shield is pure silver. The older version used silver plated copper for the shield(s). I wonder what, if any, difference this makes in the sound? One assumes they changed it for a reason?

Got a 0.5m one, with BNCs, in a couple of days ago. It replaced a generic copper BNC cable between my CD transport and DAC. This is actually my first experience with any kind of silver cable. Still breaking in, but it shows great promise, so far.
