Simulation of unbalanced - balanced converter

I using unbalanced/balanced converters with my circuits like microphone preamplifiers and headphone amp because the used chips (INA217 and TPA6120) have symmetrical balanced inputs. This is very important, the sound and the dynamics are much better with this solution. I simulated the schematic of converter, and here are the results:

With scope and AC voltmeter on real time simulation:


AC analysis:
