Worth reading this:

especially this bit:
Whilst a definite safety feature when used as designed, like all things electrical PME presents some risk potential for those tempted to idly bung in a 'hifi' earth. If the house supply is PME then idly adding a local earth spike in addition to the bonded neutral has the effect that your house could end up as the safety earth route for 10-100 houses in the area. For example in the case of a broken neutral elsewhere in area supplied by the same substation transformer the multiple bonding, and all the leakage currents from your neighbourhood's hundreds of bits of inlet-filtered equipment /SMPS now sees your hifi's earth. Do you still want to rely on your earth spike ?
UK applicable as far as I can see.
