The balanced DAC’s output must be processed by a differential stage

not with Op-Amp
that is because balanced output are not complementary

the two outputs of the converter hot and cold
are not complementary
then to make a cancellation stamp timbre
you must subtract the signals

The algebraic subtraction of two signals in phase opposition
corresponds to a sum (op-amp or transformer)

the algebraic sum of two signals in phase opposition
corresponds to a subtraction (see mixer resistors on picture)

resistances are crossed by the same current
This will clear the same DAC's timbre and digital noise footprint
In fact you will discover
which serves to filter LPF
no more
