I concur with your observation...
Because our own taste are grounded in our ears/brain neurological specifics among other factors and this is adressed in psycho-acoustics...
Then it is not only about the gear synergy and embeddings for sure...Our tastes reflect our history and neuro-biology of hearing ...
It's an evolutionary process ... not just in terms of how your equipment choices evolve, but also how you gradually learn what type of sound appeals to you the most. Honestly, when I started I had no clue what I liked. So it's not always about the synergy but also an exercise in self-exploration.
