Brickwall ground pin is only connected to this dedicated earthing and nowhere else .

Radni,
Per NEC code the Aux Grounding Electrode you have installed shall connect to the equipment grounding conductor of the branch circuit that feeds the Brickwall and your audio equipment.
What you have now is an isolated grounding electrode that is not electrically connected to the main grounding electrode system of your home. This is a violation of NEC code and the local codes in your area.
Ask your electrician in the event of a ground-fault condition of the Brickwall or associated audio equipment fed by the Brickwall, how the ground-fault current will return back to the source. The source being the electrical panel in your home.
I look forward to his answer......
Jim
