Lateboomer - I have silver cables also and the gZero6 are better - but the gZero10's are exceptional.
I think I posted in an earlier post the even the gZero3 bettered some very expensive Silver XLR Interconnects.
If the silver is used in the right place i.e. in the signal conductor, then the neutral only needs to be copper - making it out of silver is a waste of money - trust me - I have tried both methods and now my home brew cables have solid silver signal wires and copper neutral wires
I hope that alleviates your fears
