I believe you’re correct. DACs obviously can’t determine volume at all, but amps can try to use the impedance to create an estimate.
This probably isn’t accurate though. If you really want a good estimate, you would have to calculate it with current voltage output and the specs of the headphones/IEMs in question.
I’m just a hobbyist too, but my headphones are extremely inefficient so I’ve spent some time looking into this. Too bad we don’t have oratory here
Some amps do indicate how much power they’re outputting. The little portable dac/amp Qudelix 5k is $100 and does this. I think it also has fields for impedance and sensitivity, wherein it calculates SPL (dB), but I don’t actually have one so I’m not confident.
