Technically using quasi-balanced would cause little if any audible penalty in a normal home environment. The advantage of balanced is rejection of noise through common -mode rejection.

[FAQ] Which DAC output is better – balanced or unbalanced?

The balanced output uses complex class-A stages, they give noticeably better sound quality than the much simpler unbalanced output stages. The balanced outputs behave like coupling transformers so they can drive an unbalanced input provided that XLR connector pin 3 is connected to pin 1 at the end of the cable farthest from the DAC. Used like this, you may find that muting clicks are more noticeable. We recommend using the unbalanced outputs to drive an unbalanced input.
