If it's just a phase splitter and the circuit isn't balanced chances are that that particular component will most likely sound better single-ended because in single-ended input/output mode it won't have the extra parts necessary to convert balanced to single-ended in the signal path.

如果内部电路只是相位分支器，并不是平衡电路，那这个器材的声音也许仅仅和比较好的非平衡器材差不多。因为在非平衡的输入/输出模式的信号通路中，没有额外的器件用于将平衡的信号转换为单端信号。
