Very interesting post thanks.
I am thinking that musical absorption is better description of what we audiophiles do than critical listening.
Music absorption or immersion cannot coexist with a state of acoustic stress or dissatisfaction...
This is why to be put in an altered states of joy listening music Timbre perception must be optimal because it help a lot to make the union of the listener with the sound and then with the musical content affecting the body ONE experience.
Then if we do not lose our tendency to "critical listening" we cannot enter into the altered states without help (pot,beer, and friends)
It is why owning a system/room touching the minimal acoustical threshold of satisfaction matter a lot... Acoustics, it is my opinion, matter more here than the gear price...
