If RFI is a problem (and it isn't in the vast majority of home

almost never have significant common mode rejection at radio frequencies.
This is the first time I've ever heard anyone say this. Do you have a
cite?
My guess is that RFI will not be reduced by using a balanced input.
My guess is otherwise. Of course, I'm not really guessing.
Unless the RFI signal is predominantly positive or negative
(assymetrical), I would think that it would effect the + and - signal
and conductors in a balanced cable equally.
The differential input would then eliminate most of the RFI since it
is common to both legs of the signal path.
