Balanced Question: Which pin on the balanced outputs is hot? Pin 2 or 3?
My amplifier manual says "polarity is incorrect" if "bass is not spatial". I seem to have a more cohesive sound when my amp is set at normal polarity but there's more bass when phase is switched. As for "spatial", I'm undecided. So no more guessing.

You can use this diagram for the pinout of 4-pin XLR.

Is that the layout for the balanced outputs of the Holo Spring Dac or just an example photo? I imagine most use the same layout but some must not since my amp gives a choice.

I was a bit confused on your original question it seems. I thought you were inquiring about your amp's balanced output and assumed 4-pin XLR. You want to know about the dual 3-pin XLR output of the Holo.

I haven't had to make any adjustments for Holo and I am using standard 3-pin XLR cables. Pin 2 is positive.

This is from my amps manual. There is a phase selector to match the incoming XLR signal. It "works" either way but sounds different so I just wanted to verify the correct setting. It's likely the "normal" setting, but ...
