If pieces of electronics have been designed effectively with two otherwise identical circuits running out of phase it makes sense to connect one to the next with a cable carrying 2 out of phase signals and a ground. On the other hand, if the electronics are single ended using XLR balanced connection leads to the extra complication of transformer or other conversion at either end of the connection. Personally I favour the simplicity of single ended for domestic use.
