Good, then I'm not losing my mind! ;-)

As a practical matter, an unbalanced output driving a balanced input can 
have most of the benefits of a completely balanced system.  One step up is

the so-called impedance balanced output, which involves adding a single 
resistor to the source.  That usually gives you over 90% of the benefits
of 
a completely balanced output.
