There is a big difference between double blind test public protocol and simple blind test in private setting used in your own audio optimization process in an incremental number of steps , with all the time you want , all the repetition you wanted , with the music you pick which is well known to you ( for me albums i know for fifty years) and within an acoustic set of conditions you have put yourself together and which you know very well, all this in complete relaxation...
I agree with ya....I wouldn’t agree to any kind of blind whatever in some random dude’s closet with random tracks back to back. I have done blindtests in my room, where i know a) the resolution of this room is quite high, i.e. i’ve got the acoustic fields ACDA panels that deliver resolution levels a notch above anything i’ve heard (some of Dennis Foley’s proprietary stuff). Anyways, audible differences in cables are quite subtle above a certain quality threshold of build/layup/materials and you need a high resolution room to hone in on such subtleties. b) There are 2 instruments i’ve been playing for... coming up on 40 years. On specific tracks that i know very well which showcase these instruments, i am a highly skilled listener (understandably) for this purpose.
Eitherway, I did it primarily just to see the look on a ASR cult member’s face and aid with his subsequent rehabilitation. There were 2 other dudes observing the whole spectacle and laughing hysterically when i hit the 20/20 times. 😁 ASR dude probably thought me a voodoo practitioner/grand wizard as he walked out in defeat.
There is a YT channel called Alpha Audio where a couple of geeks do all kinds of listening tests, measurements, etc on different tweaks (fairly entertaining). I bet the ASR cult goes nuts when it sees that channel.
