It all makes sense. Well almost all of it.
1) What percentage of AV equipment will explode due to neutral being hooked to ground?
2) Say you have a tube amp that after the HV transformer 0v is ground. You have a DAC that has no transformer in it, 0v is -60v. A rca cable connects the two 0's which are actually 60v apart. Poof?

many distribution board systems already connect neutral to earth. In these cases when separate wires are taken to the socket outlet and one connects standard equipment, do thay all blow up? I think not!ak_47_boy said:
What tells each component that the voltage is 0V or -60V?ak_47_boy said:
They each need a reference voltage. We know that Live & Neutral are not the references (isolated from the mains). The reference between the two pieces of equipment becomes the interconnecting cable. In this situation when you measure between them you will find that each has settled so that they individually measure the same but when you measure from one to the other you will have to select a reference voltage and all your measurments will be relative to that voltage. No "poof".
But ground is hooked to the center tap and neutral is hooked to one side in balanced setup. Touching ground to neutral will short one side of the secondary.

You might want to look at pg39 of Bill Whitlock's note

He suggests that balanced power is (mostly) a waste of time and money.
Neutral is hooked to ground in many distribution systems but only in the distribution network. It's never done inside equipment. So the scenario you describe will never occur.
