The primary advantage of balanced signalling is the common-mode noise rejection. If you have ground-loops that are causing buzzing or whistling, balanced IC's can help if inserted in the right places.
It is a common misconception that you can run balanced longer without degradation. The degradation due to capacitance is identical to SE interconnects.
