I believe the Schiit Gungnir Multibit DAC XLR outputs are true balanced. With this said, in some cases as @tweak1 points out the quality of the cabling can make a big difference - in fact I recently experimented with a "decent" XLR vs a "fantastic SE" between my DAC and linestage. I compared the Cardas Clear Light XLR vs the Tellurium Q Black Diamond SE and the TQ won out hands down. While the TQ gave up a few dB gain the sound was richly organic, much more detailed, and presented a bigger soundstage than the Cardas.
I think people obsess over spending extra money sometimes for XLR connections when they actually could get better sonic gains for less incremental cost by going with better SE ICs.
