As for Mahgister’s comment about room acoustics ("embeddings!"), he/she/they don’t really solve the issue. Because room acoustics can be constantly changed, right?Thanks for your excellent post....
But you forgot ONE thing...
Room acoustic is an optimization process with a guiding rule and acoustically very precise ideal goal :
TIMBRE perception and actual natural instrument timbre recognition....This is an objective concept.... I dont change my acoustical settings without a guiding and ruling phenomenon to enlighten my perception....It is not ONLY my taste that rule my acoustical choices, it is the way an instrument must sound in a natural way...So imperfect my ears are for sure....
I dont change and dont want to change my actual generally complex acoustical settings.... Refining something yes, but a slight refinement is not a change....
If the piano sound like a real piano in your room thats it...
For consumerism i dont criticize people who can afford very costly gear.... I approve them... I would did the same if i could...
I criticize pavlovian condtioning marketing consumerism hype AGAINST knowledge of basic acoustic in audio threads...
Simple.....
For the philosophical part of your post:
I can say that i prefer Peirce pragmaticism to James pragmatism... 😊
And in the law of three for Peirce semiotics there exist a universal optimization process from the one to the many and from the many to the one....No need to choose between changes or no change but the need to OPTIMIZE this relation in synchronization with the universal optimization process...And All is one element BEFORE being many in a concrete world...And we must CHOOSE among many audio systems our OWN audio system before changing it OR before improving it by changing the acoustical dimensional controls...And it is clear that if we are pleased with the results after a successful optimization process we are free to listen to music and forgot about sound....Like we are free to buy 3 systems in three different rooms and optimize each one.... But how many will do that? And is it reasonable to profess that this rotating rooms systems are the audiophile goal?
Anyway at the end ONE of these three perfectly oiptimized audio system in his rightfully acoustically controlled room will be beter than the other 2.... Why?
Because of acoustic law governing audio system embedded in specific room with digfferent geometry, topology and different acoustical content... Then the owner of this 3 rooms/systems will be please with one over the other two because of his SPECIFIC hearing apparatus in synchronization with one among the three perfectly optimed rooms/systems...
Simple enough?
