Best ground connection

[mastermosfet]

hello,

I have a pre-amp unit and an amp unit;
What is the best ground connection between the two?
Leaving ground passing only trough signal cable shield, or paralleling it with a second dedicated ground cable?

Thanks for any useful feedback.

try this:get a screened cable with 2 signal carrying cores,ie 1 shield,2 wires.1 core will be the"signal"and 1 core will be the"ground"and the shield with be connected together with the "ground" at one side only.
