When any system gear at any price is well installed and well acoustically optimized ,then you know it because your critical listenings skills are put to sleep, they are no more necessary.
Not because your system is the best in the world, but because any well acoustically well balance speakers/room experience is highly satisfying in itself.
What irritate us is a system which awake our critical listening attitude because we perceive clearly an unbalance set of factors,..
If we adress them and takes care of the acoustics problems, our critical attitude go to sleep and we listen music not sound defects.
Any system gear/room at any price well done will gave pleasure...
Acoustics rules audio... Sorry for the sellers of gear upgrades...
i could upgrade my 1000 bucks system (not the headphone it is the best in the world ) i dont need and dont want to... I call that the minimal acoustical satisfaction threshold...
My budget is limited and i must listen nearfield with small speakers now. but i felt no limitation, because it is OK acoustically for timbre, holography etc...
my top system choice anyway for music now is my headphone which beat most speakers system save top speakers in top room .
