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.

That was my impressiuon few years ago...

i dont stay there a long time... 😁😊

But one dude impression is not truth...

But from the beginning of this thread this look like if not truth at least a possibility..

Then the master has created his disciples crowd and it is not the disciples who are at the evangile  distorted origin : only measures means anything...Throw ears, golden one, or  Karajan ears or mine in a dust bin...

Anyway it does not take a genius to know that measures alone dont equate to a good sound when you add mutiple components together...

.

I’m okay with measurements used in proper context but I don’t respect Amir any longer because he clearly and obviously evades answering important questions. He simply ignores matching components during his reviews which misleads many others who don’t know any better. He’s closed minded as far as I’m concerned. They’re really an extremist bunch.

In a recent test Amir 'beheaded' a product (i.e. lowest rating) because it had an unacceptable 0.003% distortion. Can anyone can hear 0.003% distortion, are any speakers possible of even 0.03% distortion? What about 0.3% distortion? I have since listened and bought the product, it sounds wonderful, several others agree, the measurements have spoken,  but what do they mean?

As long as THD+N is below audible range, who cares? The only reason to worry is when impacts the sound in an unexpected way.

"So, playing a piece of music the subjects don’t know on a system that is not like their own and asking them to compare that sample to a slightly changed subsequent sample is a waste of time, not a universal truth. Most of us have several pieces of music/performances/albums that we know intimately. If the benchmark used is one of those on our systems (or an equivalent one), then comparative testing has validity, but only then."

 

SIMPLE SOLUTION:  PLAY THEM A PIECE OF MUSIC THEY DO KNOW.

 

Blind testing is nothing to do with measuring.  There are no measurements involved.

Claims by an individual to hear a difference are only valid as opinions of that individual.  Not only could he be wrong, he could be knowingly lying.  Such claims can only be validated by blind testing.  This proposition is so simple and so obvious that it does not need six pages of debate here.

You are wrong here...

You must use the same system and not only the same music...

And it is not enough at all...

We are USED to acoustic very precise conditions in a ROOM, our room, which by far affect the sound quality more than each piece of gear UNBEKNOWNST to most people because they dont pay attention to acoustic...

 

Comical....

No one own "golden ears" but we all own our listening ability BECAUSE of our hearing HISTORY circonstances and IN some KNOWN ENVIRONMENT WITH our specific audio system...Buy an acoustic book and forgot blind testing fetichists...Learn how to tune a room and you will spare money...

Only ignorant people in acoustic and psycho-acoustic imagine that people pretend to have "golden ears"... Save some reviewers in audio magazine another kind of fetichists who vouch more about gear than acoustic science also...They need golden ears to sell... I dont sell anything, i need my ordinary ears to LEARN and be acoustically creative...

My normal ears deetect any change in my room condition even a straw introduced in the room in some location why?

Buy an acoustic book and read about Helmholtz resonators and you will know...No need to have alleged "golden ears" at all.. these accusation against people come from ignorant people...The gear reviewer tasting fetichist is ignorant like the meaasuring tool fetichist... The two groups IGNORE acoustic learning experiments...

Quit those fools measauring noise with a tool to decide if a dac is good without any listening controlled acoustical experiments to compare them after this "measuring" feast ...

If you want to blind test everything, it must be in your room acoustic condition with your system and a music you know by heart..but it will be a lost of time and IMPRACTICAL...

How do you think i was able to optimize and tune mechanically 100 Helmholtz tubes generators and diffusers one at a time ?

Golden ears my a....

Blindtest my a....

The reason is my listening learning history of EXPERIMENTS  in my room with my system and my music...

Do you imagine that a piano tuner must use blindtest to tune a piano?

 

😁😊

Acoustic ignorance is the ONLY audiophiles or pseudo-scientist measuring fetichists COMMON problem ...

Easy to verify...

if you are a "clear thinker" i am sure you can figure all that by yourself...How is it not the case already?

You read too much about gear and blind test... Not enough about acoustic and psycho-acoustic ESPECIALLY..

Is it easy to figure out ? NO

You need to be a real clear thinker...It takes me 2 years alone , much time but at no cost...

my 500 bucks system give me ALL acoustic factors: natural timbre, dynamic, clearbass, 3-D soundscape filling the room, depth imaging, listener envelopment/sound source wodth ratio or LV/ASW ratio, intimacy like with headphones superior to me 8 headphones with a sound out of my head AROUND me... I am in some recording AMONG the musician on the scene...

500 bucks system few bucks dac, vintage amplifier a very good one and good speakers paid 50 bucks... Is it the best system there is? Not at all half people here own a better one...but it work in OPTIMIZED acoustic condition...I am not envious of ANY superior system why?

Because there is a TRESHOLD of acoustic qualities, a MINIMAL threashold from which you are HAPPY even if better system exist.. Why?

Because your ratio S.Q. / price is OVER THE ROOF...

Is it not clear?

 

is it not good?

Thanks to acoustic and psycho-acousatic BASIC elementary knoweledge...

I dont boast about my gear here, i never did, it is relatively only basic very well chosen gear ,i dont even name it here...

I thanks acoustic science nothing else..
