Choueiri did not invent acoustics...Even if he is a genius...And he is... Reading his articles...😊
His filters gave us to perceive what i already learned to perceive in my own room experiments about spatial qualities...( but i could not and cannot eliminate completely crosstalk mechanically even if i tried 😁)
Reverberation is key, listener envelopment (LV) and source sound auditory width (ASW) are for exemple factors about spatial qualities most people who never played with acoustics of their system/room had no perception because they dont had the concept.... We cannot perceive clearly what we had no concept for before the perception.
And the BACCH filters cannot replace our room acoustics or make a bad recording greater about all acoustics aspects which were never recorded appropriately to begin with ...
I dont have the BACCH filters myself nor did i ever heard them but because i experimented 2 years non stop with my room all aspects of sound described by Choueiri make perfect sense to me when i read his article..
Most audiophiles know only superficial aspects of sound : imaging and soundstage which are anyway only external manifestation of these 14 acoustics qualities under controls, spatial and non spatial one...
