On another thread, Elizabeth brought up a subject, that is typically ignored in these conversations. ie: Familiarity(with the system being altered/used as a test platform). Hours spent in a car familiarize it’s owner with the overall sound of it’s operation. Slight perturbations/changes in those sounds, will usually go unnoticed by an infrequent passenger, but will(generally) be obvious to the owner. My system’s presentation has aspects, with which I’m intimately familiar, when reference material(call that a, "control") is played. When something(fuse, cable, outlet, vibration control, whatever) is replaced, and that changes an aspect of my system’s presentation; it’s going to be much more noticeable to my ears, than anyone else’s(again: usually, because- there are variables). Einstein theorized/realized(and it bugged him) what The Hubble Space Telescope confirmed, in the 90’s. ie: Around 95% of our universe, is comprised of stuff, no one understands or knows how to measure(but- to which unexplained phenomena point). (h
ttps://home.cern/science/physics/dark-matter) I have no problem, trusting my ears to tell me when/if things have improved in my system’s sound(unexplained phenomena/various controversial means), without knowing the precise mechanism. No one has ever proven(or- categorically disproven) anything, through endless theories, conjecture and rhetoric. Theories are proven through experimentation and measurement. But- you have to know WHAT and HOW to measure. In the case of expanding our musical enjoyment, it starts by listening to something new, if we care enough. Anyone’s having convinced themselves otherwise, through whatever process, should not dissuade another(that cares about sound) from experimentation.
