I guess it might be possible to calibrate an amp for true volume if you calculate it, assuming such a feature exists (I never actually owned a dedicated amp, much less a fancy one, so I have no clue if such a feature exists), also I assume that overtime headphone efficiency will reduce as the permanent magnet gets weaker if exposed to high heat (no idea if forgetting the headphones in a car in summer would be hot enough to make a meaningful difference though) or dropped repeatedly (though I'd wager the headphones will stop working before the magnet itself in such case).
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.
That's pretty cool.
