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’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.

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...

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.
