SMSL SU-1 design idea

Is this in a SU-1?!

If I read posts carefully about all affordable (well measuring) digital audio devices have very poor XO’s as a standard. Now it would be relatively easy to change such things but the staccato way of working instead of a total make-over does not work for me.

Yes, it is SU-1. But sorry, I tried so hard to write, but in the end I couldn't get a good example. I can't transmit it through this ADC. In the future I'll think about an option with microphone recording. Maybe post here then again. Perhaps altor right and it's just an illusion, but why do I get such a big residual difference when subtracting the inverted signal? :headbash:
