Looking at ADI-2 and practical listening levels - not at all from the amp side!
But:
Yes, and the only reason for a difference is the cable architecture:
Single ended often uses 3-wire-only cables, sharing one wire as common ground.
The internal resistance of this wire causes a significant, audible increase in stereo spread due to inverted signal crosstalk between left and right side.
If, for single ended, a 4-wire cable is used like it‘s mandatory for balanced, on ADI-2 there‘s absolutely no difference in signal quality.
Just much more excess power, that stays unused.
The IEMs you linked uses 4-wire cable, as can be seen in the picture.
Run them single ended with ADI-2’s “Lo Power” setting and you’re fine.

Yes, of course, ADI-2 is very powerfull, and it’s up to 4 times more likely balanced than single ended, as balanced has up to 4 times the power.
But you can limit the power with the above mentioned “Lo Power” setting, then you’re safe.
