An uncountable multitude of ways to deconstruct the mentioned “sound” of a transducer. Tailoring like this will work for the ear and skull proportions, neural feedback (etc) of some and fall for some.
Audio reproduction circuits are complex enough, the sensory system is so complex that we’re just flaking the surface in trying to understand.
Studying these relationships in depth is quite a science.
(Though even without experience I blindly trust that SET topology is a very good alleviation for most problems people have with tolerability to sound sigs, when care is taken with matching)
