My answer will be complex because you are right and wrong at the same times..
Yes we own our own ears inner filters each different from other person , our heads dimensions and ears distance and geometry differ too...
Our personal listening and hearing history differ too..
Then we had each one of us our biases ... You are right on this ...
( it is the reason why, ultimately small room acoustic COULD BE tailored made for ONE pair of ears and is very different in acoustic application from great Hall acoustic, as headphone measured for Smyth realizer or for the Choueri Filters must be very specifically tailored made experience for one specific pair of ears )
But where you are not completely right here, it is by the omission of acoustic and psycho-acoustic laws or principles which are the same for everyone..
The only way to learn which is timbre , apart for recognizing a good timbre subjectively by memory and training , is learning how to control the acoustic factors modifying it... it is the same for all other aspects, as dynamics, transients, imaging differentiation , soundstage varying dimensions , holographic volume of sound source , immersiveness etc each of these factors cannot be understood if we do not learn, not only how to recognize them, but how to modify them...
How can we experience immersiveness, the most important factor with Timbre, which is a very specific acoustic factors defined by ratios of timing, and distance , and ratios of reflective/diffusive/absorbing surfaces, and relative to the pressure zones specific dynamic in the room , and balance ratios between sound sources and the listener position , etc ?
It is the reason why it is acoustic and psycho-acoustic which is at the center of audio experience FIRST , not the gear electrical performance as Objectivist claims erroneously or apparent sound performance and qualities and their price tags as subjectivist claims erroneously ...
Snobism is based on two factors : ignorance of what is really important and exclusion of those who dont recognize the arbitrary factors constituting snobism as a selected club where some sheep thinking around a secondary factor is elevated to idol status...Objectivist and subjectivism may become snobism clubs based on different orientation which can be meaningful when relativized but whose meaning is erased in quarrelling meaninglessness..
Then acoustician cannot be snobs nor could we think they are only because they know better than objectivists or subjectivists..
The right answer in audio is this one : use your ears to verify information and to train them but base your journey on experiments more than just purchases of consumers good ...

@mahgister (IMHO) recognizing ‘good sound’ on a superficial level is about hearing sounds you’re most familiar with. So human vocals. Maybe an instrument if you’re a musician. How does that sound coming out of the speakers compare to the ‘real thing’? You may entirely disagree with me and value bass or soundstage or micro details. There’s no wrong answer. Only snobs think that they have the right answer. It’s subjective I guess.
