If by “bal cable” vs. “SE cable” you mean 4-wire vs. 3-wire (Y-shaped GND or “return” wire), yes, there absolutely is an advantage: it reduces crosstalk between the L and R signals by a mathematically demonstrable amount. So it can get you some part of the benefit of “going balanced” without actually “going balanced”. But you will probably not hear the difference if the drivers have hundreds of ohms of impedance (those are already good enough at rejecting wire-generated crosstalk, they don’t need extra help).
