Then generally "audiophile state of mind" is linked to the next upgrading gear cost... As illustrated by the OP statement...
"acoustic state of mind" by contrast is motivated by real listening under control experience and experiments at no cost or peanuts costs...😊
"audiophile state of mind" is not really aimed to sound improvement often but to gear design improvement...
Acoustics is not reducible to gear design quality...
In the three equation part : ears/room/system, the pieces of gear are, so important they may be and they are, secondary... ( especially when a synergetical basic system is available already at a relatively low price according to your budget)
I bet to be one of the rare one saying it this way and clearly ... 😁😊😋😎
