This cable connects the ground of the circuit (via a phono plug neutral connection) to the ground pin of the Mains plug
Why? - Some circuit designs do not ground the neutral side of the circuit to the ground pin so there can be a noise buildup in that circuit
Grounding in this manner will ensure the neutral side of a connected circuit is grounded effectively - reducing the overall noise level
It provides a good solution to one aspect of the various noise related issues in a system
I have applied a similar DIY solution to components with wal-wart power supplies or have a two pin plug (no ground) and it proved to be very effective
Now, all of my components have fully grounded circuits - so there is no need for this type of solution
When to use them?
- Check your component to determine if there is continuity between the neutral side of an input/output socket and the ground pin of the unit - if there is, there is no real need for one of these cables, but it will not be an issue if you still decide to use one
Gutwire make some very good power cables - this one goes one step further
Using this type of cable on every component will not create ground loop issues - if you have a hum while using this type of cable there is something wrong with a connected component - it is not the cable creating the issue
