Nsgarch...OK. I'll bite!
Balanced output provides twice the signal, but twice the circuit noise as well. Since signal/noise ratio is what matters you need to find another reason for balanced. A balanced interface avoids noise pickup in the wires, and only the noise picked up in the wires. For a 1.5 meter run this ought to be a non-issue.
FWIW, I do use some balanced lines, including 25 foot runs to my power amps. Why? Because the electronics have that kind of interface. Results are no different from single ended, in my case.
