To get a clean sound you must have a source DAC with XLR balanced outputs
But we must know that the drives are not complementary P and N
they are composed of the same identical semiconductors
but driven by a PCM digital number in opposite phase.
So to cancel the print tone of the Digital to Analog converter
must operate a subtraction
NOT A SUM
this is possible by using a potentiometer for the adjustment of the listening volume in series with a resistor of equal value
suggest 1K

NATURAL MODULATION
that PCM CONVERTER is born with wrong way
IS NOT MADE FOR AUDIO
we must know that the drives are not complementary P and N
as Law of twice denied would.
this means that the method of complementary
must be applied in a manner opposite
To qualify for compensatory timbre of the two systems

You are wrong. DAC cips are build in CMOS technology - complementary-symmetry metal–oxide–semiconductor.
And anyway, that theory canceling with P and N applies only for amplifiers final stage working in AB class. Nothing to do with DAC output that is a class D type (because of the Pulse-Modulating signal that reperesents). The digital signal is... digital, there is no "ballanced" PCM or DSD.
Read a book, something...

The current of the PCM1796 on each of the output pins (IOUTL+, IOUTL–, IOUTR+, IOUTR–) is 4 mA p-p at 0 dB (full
Scale). Differential Current Output: 4 mA DON'T MEANS COMPLEMENTARY OUTPUT

To find out if I'm right or wrong, just do a simple test -
a double potentiometer connected to the balanced outputs, stay around the middle of the range, the more you are close to zero is the most effective cancellation -
then turn up the gain of the amplifier with inputs unbalanced RCA
try to hear what happens to the sound:
a magical horizon suspended in midair generates sounds

no need for experiments, its pretty basic electronics that pin 1 is for shield/chassis not signal ground. if you need to connect an RCA output/input to a balanced input/output, use an instrumentation amp or transformer, which ever is suitable, dont try and make a magic cable do it
