If my amp and preamp were fully differential I would care, but I’m single ended. If I had balanced amps I would probably seek out gear that was also balanced.
As others have said there is a lot of gear that has XLR outs that aren’t really balanced. My DAC has both. They both sound identical and are the same output.
It’s a $1600 up charge for a “balanced” output. They clearly state it in their literature, but for that much I would go up a rung up the DAC ladder.
