Define differential and balance in that case !

One very im****tant difference is that balanced circuits should be of equal
impedance on both legs. This is not a requirement of differential
circuits.
Here lies a very im****tant difference as to how they function and where
they
are most or beneficially applicable.

NO. That's a floating circuit and as long as it's screened there
absolutely
NO reason it should hum whatever.

Not necessarily with regard to voltage to ground though !        ;~)
Absolutely not in fact. Think how telephones work.

Not quite sure what your point is there.
