Sound experience means something in some room for someone...
Change the room and you can prove anything.....The differrent devices has NO Sound of their own which stay the same in different room....
Blind tester audiophiles are deluded like people who vouch blindly for a piece of gear INSTEAD of acoustic embeddings controls...
That is my experience....
There is no objectivist nor subjectivist in acoustic protocol experiments....Subjectivity is CORRELATED with objective measures ALWAYS...Subjectivity is not ERASED by objective measure save for idiots...Idiot dont study acoustic with their EARS anyway....They trust a limited tool like other buy costly "tweaks" or branded name of costly gear...
Acoustic is the only key in audio....
