I don't think this is factually correct. That analogue signal is what you'll eventually hear. It'll get amplified and speakers/headphones will simply show what it is
I'm not sure how many DACs have you heard, but the odds are that a $9 DAC compared to a $3'500 device that measures very similarly still would make a noticeably different sound in the same setup.
Just to be clear, measurements are useful as extra data points and there's certainly place for them, but to many users who compare DACs these perceptions reflect their actual performance.
As long as we can keep the conversation civilized you should be OK
For a second there I thought that you had something entirely different in mind and related to an artist's intention etc. As for measuring tests, they're objective in the sense that you end up with numbers you can compare, but the question is what to do with that info then. If that's the primary factor to for you to consider a specific DAC, that's perfectly fine, but many of us here would still like to actually listen to it and see whether we like it in our setups or not
