And the most interesting no correlation between the prices of the systems and sound quality. Actually most super expensive rooms on shows sound horrible!Electronic audio engineering has matured long ago...(50 years at least ? )
Very good gear with audiophile S.Q. potential exist for many decades at low cost...
But on the other hand ACOUSTIC of small room is underestimated by most and in my experience only passive material treatment is used and often not in the right way...
Acitive mechanical controls of small dedicated room cannot be an easy market because most system are in a living room not in a dedicated room ...Sellers of acoustic products dont have the time to fine tune a mechanical adapted grid of mechanical Helmholtz device controls...It is more financially interesting to sell ready made bass traps, diffusers surface, or reflecting surfaces...
Then the fact that highly costing system sound bad or horrible is often because the room where they are is uncontrolled, if minimally treated, and absolutely not prepared acoustically for the specific demands of the specific speaker...
It takes me many months to fine tune my room... an expert acoustican will make it in hours...But hours amount to many thousand of dollars + devices cost+ +material cost.... Then it is not surprizing that some sellers ask for 50,000 bucks to transform acoustically a room for dedicated audio room listening....
Acoustic is the sleeping princess and all the pieces of gear are the 7 working dwarves...
We listen WITH our system but THROUGH the controlled room/speakers...
Most people think the opposite:
They think they listen WITH their uncontrolled room/speakers ,THROUGH their system....
😁😊
In a word, the sound experience is in the ears/room not in the cables, dac, or amplifier....
They put the cart in front of the ox....
The ultimates reason is simple: money... It is more financially interesting to sell new gear for the living room and more easy to plug it on the wall and listening to it , than investigate acoustic and psycho-acoustic science control in a dedicated room...
