As an electrician friend of mine described it "excess power is put into the ground rather than returning it to the national grid (via the negative cable)".
Bzzzz. WRONG! You lose 10 points!
I didn't know you still had DC supplies down there either.
Most equipment made in Asia has twin flex and no earth. By adding a separate earth wire (soldered for example to the outside lug of an RCA plug) we get a significant improvement in sound.
Well, it can help reduce hum and other interference, so we're getting somewhere now.
The earth cable is directional so try it both ways (take a walk on the wild side). Cable that is directioned correctly will sound â€˜fasterâ€™... ignore all other aspects.
Oh dear. Now he's gone and spoiled it.
I wonder where can I buy some of that fast cable?
