Amir and Blind Testing


Let me start by saying I like watching Amir from ASR, so please let’s not get harsh or the thread will be deleted. Many times, Amir has noted that when we’re inserting a new component in our system, our brains go into (to paraphrase) “analytical mode” and we start hearing imaginary improvements. He has reiterated this many times, saying that when he switched to an expensive cable he heard improvements, but when he switched back to the cheap one, he also heard improvements because the brain switches from “music enjoyment mode” to “analytical mode.” Following this logic, which I agree with, wouldn’t blind testing, or any A/B testing be compromised because our brains are always in analytical mode and therefore feeding us inaccurate data? Seems to me you need to relax for a few hours at least and listen to a variety of music before your brain can accurately assess whether something is an actual improvement.  Perhaps A/B testing is a strawman argument, because the human brain is not a spectrum analyzer.  We are too affected by our biases to come up with any valid data.  Maybe.

I beg to differ that the “amateur with an analyzer” site is doing a service, because he makes errors that manufacturers point out.  
 

There are actual, ethical, knowledgeable people doing tech testing that serves the community.  Take this guy for instance, that many in the high end video monitor world respect, even the professional color grading forum I participate in mentions his reviews.  https://www.hdtvtest.co.uk

He has no agenda, unlike the amateur being discussed, who sells cheap gear.  
 

 

On the other had, amir will not stopn those will grow past him, after they spend time on the website. Slowed down, for some, maybe.

Even stereo review served it's purpose. Not all of it was bad, or could be.

Those with a tenancy to grow beyond his website, will do so.

Here’s a perfect example. Teo Audio is truly innovating in the world of audio reproduction. But does your cable show measurable results of what it does?

It would be fantastic if it did, but my guess is that the human ear is needed to detect the benefit of your product, and it must be in an appropriate level system. Would you send them of your cables for “review?”. My guess is not. It would be like sending a Ferrari to a car review site whose criteria is gas mileage (but who can’t seem to consistently measure milage correctly, or worse proclaiming the Ferrari is inferior to the yugo, since it “tested” better.

Astounding!

Who believe that the only main factor in sound/music experience is measured electronical sheets ? Suggesting that ears experience in audio is useless is beyond preposterous...

What we hear in a speakers/room system is determined by acoustic and psycho-acoustic science ...It is determined by the rigourous relation between the resonant body of a sound source, a speakers set or a musical instrument, and the CORRELATIVE subjective impressions of a musician, a listener; or for example the ears/brain experience of a customer of a watermelon fruit sellers on an open market tapping it to let know to the customer if the fruit is in a state before being ripe or after being ripe...The human ears can INTERPRET with sound experience the QUALITIES pertaining to a distant object or an invisible hidden object ijn the dark...

Only ignorant people think that a mere part of a frequencies bandwidth in a piece of gear measuring well is ENOUGH to define what is "sound" and what is "sound experience"...Actual science cannot read a large spectrum and decipher it like the ears/brain do in a second and declared that a piano is such and such, or this violin such and such, or this room is acoustically such and such......Or this fruit is such and such after percussion , or this metal bowl of such quality after percussing it and let him vibrate for the ears.....Instrumental TIMBRE is not REDUCIBLE to a spectrum ONLY..

It is the reason why i quit reading this technocratic pseudo science hobbyist site ... The first chief hobbyist is OK, nothing bad to say, but the bunch of disciples create a void around their guru ...

I use my ears .... Any piece of gear must be listened to to be picked by me and judged ... A child may know why.... A technocrat like Amir can ignore why by profession, especially a digital designer... But an acoustician use his ears in a controlled room to adress the alleged quality of his stereo system BECAUSE he is a scientist specialized in the "sound field" studies...

The ears dont need "bits" after all and they dont hear "bits" anyway...Stereo gear system MAY need "Bits" to be TRANSLATED for sure...

Us we hear this acoustic and psycho-acoustic TRANSLATION...A Dac can REPRODUCE "a sound" by Fourier discovery about waves ...But the speakers/ears translate them to the human ear/brain like an acoustic musical instrument does instead of speakers, and the ears/brain INTERPRET QUALITATIVELY this acoustic language coming from the concrete resonant body, speakers or violin, he interpret them in music or speech and attribute them some qualities...

Sound is way more complex phenomenon than mere "waves"....If not, psycho-acoustic will never exist to begin with....Acoustic dont explain sound and music WITHOUT psycho-acoustic studies... Perhaps there is more about the ears than mere "bits"...And the brain is NOT a mere Fourier analyser... We dont understand what is sound, mastering technology, being it nuclear bomb or digital technology dont prove that we understand quantum mechanics meaning and the universe no more than this explain sound perception...

The reason why A.I.will stay a mere "tool" forever, save on the planet where people could be so stupid to renounce their creative freedom for a master , and for sure this possibility exist, the reason then is : MEANING...

Meaning exist when the part is intricate in the whole and the whole completely intricate in the part, It is possible for the human mind to DISTINGUISH between the whole and the parts, but the human mind never SEPARATE them completely.... He can forget one for the other for sure...One part of the brain can work OVER the other... 😁😊 But forgetfulness is not complete separation...

A.I. is powerful because it can work in a CONTROLLED environment where it can mathematically distinguish parts and wholes BY SEPARATING THEM mathematically ...The map become the territory here and the territory can be transformed in a perfect map... Why not, it is only mathematical play ?

A.I. is and will be a tool, but an unhabited machine haunted by a ghost or a soul for sure, and anyway the sorcer apprentices will call them mere ghosts... Concrete details we dont need on the map, or a map so real it lack only some abstract useless details...Like love, freedon, souls, beauty, non logical truth, etc...

Yuval Noah Harari, a transhumanist historian said that human have no souls nor freedom and can be hacked by A.I. and will be...

Then we can be intelligent like he is and blind to meaning and reduce meaning to INFORMATION....I prefer to stay "stupid" than this kind of "intelligence"...

The whole and parts mutual participation are manifested "meaning" for the human mind able to "fly over " the world hyper space and perceive instantaneously qualitative experiences where the distinctions can exist but WITHOUT ANY COMPLETE SEPARATION EVER... Exist only for us humans a temporary forgetfulness of the relation between the encompassing whole and parts, this forgetfulness , the Buddha and the Christ called it back to his roots anyway...

The body is the soul, but the soul is not reducible to the body....The sound is the music but music is not reducible to sound...We can distinguish the two but cannot separate them...

An information engine can work only by SEPARATING body and soul, one is real for a machine the other is only an animated ghost it put in a corner...It is a MATHEMATICAL EXORCISM ....Very precise one and it work completely and successfully...

Technology is powerful but only small mind confuse science with technology...

The center of mathematic is divine, the peripheral is human work....
