你意思係米用左AV-bypass 會唔會有電流聲?

如果成個電路係有干擾，就算去到2ch amp 都會有，因為都係由RCA 傳過去

Point of view on electrical part, i think the current sound would be produced on speakers due to bad contact or magnetic field affected.

The noise is caused by a phenomenon called ground loop. It has nothing to do with bad contact or magnetic field. It is so caused by multiple paths to the ground. That is why some Ching would simply cut off the earth wiring to prevent it from happening. See below link for more info

Noted. understood.
I understand that interference ( 220V power create magnetic field to cut signal cable ) is affect extra low voltage system. Now i understood the ground loop is difference with interference.
However, thank you for your information.
