There is one thing you seems to not understand here ...
Double blind test are not practical for everybody in his OWN room with his OWN gear and his OWN listenings habits ..
Blind test are useful practice in many industry for his statistical signifiance...THATS ALL ...
Blind test are useless for an individual incremental step by step process of tuning an audio system/room with many devices ...
Supposed now in an experiment i put a piece of shungite on an amplifier...
This amplifier is mine , the system is mine , the acoustic room is controlled by me for my ears ...
I listen and i recognize a difference ( positive or negative) with or without this piece of shungite on the amplifier ( i can ask my wife to put it or not on the amp ) ... I will use a piece of music i know very well on my room /system doing this ...
If i do the same experiment with a piece of quartz, i will recognize or not a positive or a negative difference or no difference at all ...
But it will be with my gear and my acoustic room ...
With another gear, another room, another music ; this test will have no meaningful result ...
We can do it statistically with a crowd using the same system and room for all and had results which will be positive in a low % for the perception of an effect and change ...
But this low % of beneficial results will in no way change or contradict the value of this positive results for my ears, with my specific gear, and my specific room and my music ...
Then we must not infer that a negative % results about a "tweak" means that the tweaks had no value ...
It is not also good science to infer from a mere placebo explanation... It will be simplistic and the usual way hard core objectivist simplistically eliminate a real perceived effect in some conditions for some ears as illusory ...
i dont believe and i dont buy tweaks by the way ...
I created mine at no cost ...😁
Experiment is science ... using statistic goes both way it can establish the value of a result or discredit a result as easily if you know how to falsify anything with statistics ( half of medical articles are made this way paid by big pharma ) ... See big pharma criminal methods use of statistic and this is a fact confirmed by many direc tors of the more prestigious medical journals ...Google it ..😊..
i am neither in the crowd of subjectivist audiophile nor in the crowd of objectivist ...
Sorry ...
I enjoy music at low cost by my own creative effort in simple way adressing electrical noise floor, mechanical vibrations/resonance and acoustics my own way AT NO COST ...
I dont promote scientism but simple experiments...I promote creativity not costlier upgrades ...
Dont sell me your blind test salad to discredit anything ...😊
We must learn how to hear even as adult ... It is enough for me ...I dont buy the accuracy salad on the limits of hearings... Because it is not even wrong ...It is beside the main point : qualia recognition and interpretation ...
My low cost system is enough for me as i tuned it by the way... It gave me minimal acoustic satisfaction passed this minimal threshold ... The only upgrade i need will be the BACCH filters you already own...
my best to you ...
cool. So you accept the use of double blind listening tests as a valid protocol.
