the only hiccup would be a polarity issue because the standard for balanced connections is not the same from brand to brand you may have to reverse the polarity to maintain proper polarity because they may be wired with different balanced polarities.
In this case, no hiccup.
XLR pin assignments for the Aqua HiFi DAC and Schiit Audio amp are the same:
Pin 1: Signal ground
Pin 2: Signal + (non-inverting)
Pin 3: Signal - (inverting)
