If there is some OTHER form of distortion Amirm is not measuring for that would be audible...what would that be?
I am pleased to inform you that the distortions coming from the room geometry, topology and acoustic content pairing with a specfic audio system is very powerful impediment to S.Q.... More powerful than comparison between relatively good electronic design subtelties measured by Amirm tools..
"Gear brand name subjective fetichist" like "tool objective measuring fetichist" ignore acoustic and psycho-acoustic and take the ears/ room to be unimportant way less than a decimal in THD+N amplifier specs for example...
This is called losing sight of the tree looking for an ant....
Yes it is useful to see an ant on a tree....But it is foolishness to never pay attention to the tree..
Distortions is not an electronical notion "per se" it is first and last a psycho-acoustical notion...Electronical design distortions concept come from the measured hearing human range perception and qualitative evaluation and subjective judgment guiding necessity ...
No piece of gear sound the same in different rooms...
An anechoic chamber is an experimetal room not a listening room..
There is no STANDARD room, all small room are different and own different acoustic positive and negative potential..
Then evaluation of an audio product not only is relative to human ears "specific" innate distortive potential working and history but related to specific room negative and yes, unbeknownst to most, sometimes to the positive effect of some distortions when they are controlled in some range and timing ratio for psycho-acoustic reason and experiment...
Acoustic is at least at the same level of complexity than basic electronic ...
I dont speak about common rule of placing acoustic panels on a wall here when i speak about acoustic... 😁😊I speak about something a bit more complex to say the least...Physical acoustic and psycho-acoustic of small room is not less complex than amphiteater acoustic architecture but in fact perhaps more complex because it must be designed for a specific audio system only and for the singular pair of ears of the owner room......
