Balanced wiring only gives you an advantage if the
equipment is balanced. With clever wiring it's only
actually necessary for either the 'sending' or
'receiving' equipment to have a balanced input or ouput
but you need to know what you're doing in this case.

I know the strong advantage that balanced inputs give, but what advantage do
you get from an electronically-balanced output driving an unbalanced input?


Provided you have an appropriate balun, like a transformer at the
input, you get all of the advantages.

You don't even need a balun if you wire it to take advantage of the balanced
output. Just take the balaned output (low/cold) to the destination input 'ground'
and the output (high/hot) to the destination input and do not connect the screen
at the destination.

No longer balanced - not even a tiny bit.

It's differential and for all practical purpose does the same job.

No, it isn't. You have one wire shorted to ground, and the other
terminated with an amp input. The two wires are no longer equal and
opposite, so what should be common mode pickup becomes differential
mode.
