Single Ended DAC vs Dual Differential XLR DAC

Hi,

will a dual differential XLR DAC (with i.e. 2x Left DAC chips + 2x Right DAC chips) always sound better than a Single Ended DAC (with i.e. 1x Left DAC chip + 1x Right DAC chip) assuming that they have the same DAC chip model and same board design (except the dual circuitry of the XLR version)?

The XLR has twice the output voltage, but will pure audio quality be certainly superior to the Single Ended version?

Thanks for your opinion!
