Yes.
It probably depends on the laws in your country as well, over here the DCR of the earth conductor from the MEN link in the board to the furthest switched outlet, must be less than or equal to half an ohm.
A 2.5mm sq twin and earth cable has a 2.5mm sq earth conductor.. 4 and 6mm sq twin and earth cables use also a 2.5mm sq earth conductor, highest impedance that you should see will be less than one ohm (shorted active to neutral at the outlet and measure DCR of that loop at the board). Less for a shorter run, and less again if you use a 4 or 6mm sq cable. It stands to reason that the maximum resistance between your fridge and your dedicated hifi outlet will also be less than one ohm.
We have an MEN link system here (Oz) where earth is tied to neutral at the main switch board, this reduces the impedance between this point and the star point on the distrobution transfomer, say 12ohms without MEN and maybe 0.2 ohms with.. allows for a higher fault loop current and ensures proper operation of ciruit breakers, good for safety but also means that the neighbours fridge is pretty close as well.
I like the idea if isolating transformers and also AC regeneration.
