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.

We cannot measure the difference between a middle C, played on a properly tuned clarinet vs. a synthesizer, vs. a trumpet. Your brain knows which is which immediately. Just like humming the note and singing out, wide-mouthed would measure identical, but you know they sound very different. 

Nor can we measure the vibrations our body picks up from places other than our tympanic membrane. (bones, hairs, nerves) Spatial awareness in ingrained in us through evolution. A noise, rustling in the grass on the savannah is a matter of life and death. Our ears are only a piece of the "listening" equation. 

I've played with EQ and a spectrum analyzer to make the response curves of Magnepans and Klipsch horn-loaded box speakers measure the same in my seat ...and they sure don't sound identical, though no frequencies are missing.

No measurer can ever tell you which one, out of 2 pieces of gear sounds better. (however you define it.

It's trivially simple to measure the difference between a clarinet and a trumpet.

 

I once wasted my time watching a video “review” of some audiophile switches. It was half an hour of blah blah blah about how his measurements demonstrated without a shadow of a doubt that there was absolutely no measurable difference between X Y and Z switches therefore it was impossible to hear any difference so it was all in your small “audiophile” brain, his mantra so to speak. Then he went on to briefly demo the switches he had just “measured” in his (joke of a) system. And guess what: he could clearly hear a difference. His wife could hear a difference. According to him the audiophile switches sounded significantly and audibly worse.

Without realising he had just contradicted and refuted his half hour case for “it’s in your head”. If he accepts that his experience contradicts his measurements, for better or worse, then his measurements are flawed. For me Amir became irrelevant after that video.

 

Somebody’s sarcasm detector is badly broken.

Acoustic did not is reducible to psycho-acoustic science...

Psycho-acoustic science dit not reduce itself to acoustic...

Great posts thanks.... Gear fetichist tasting group and measuring tool fetichists perhaps will understand something....

A timbre is not a tone...A playing tone is made of two phenomenon then...

Amirm is doing a terrific service to the audiophile community.

You don't have to bow to him as a "cult leader" (ridiculous meme going around) or believe everything he says is beyond critique.   His reviews are quite well vetted even on the ASR forum, where his methods and conclusions are examined.

But taking on manufacturers claims and to the extent possible examining what objective evidence can be gleaned or not in terms of measurements is providing one hell of a lot more information than we are finding in most other places (manufacturer's marketing most of all).

There is a part of the Golden Ears crowd who have an almost mystical belief in their own incorruptible, observational powers - "science can't tell me I'm wrong!  I EXPERIENCED IT."    Those people will likely never be reached.  

 

And of course as I've argued many times, no audiophile has to pay any attention to measurements or science - we can all buy whatever we want, for whatever reason.

But Amirm is providing some extra information for those who seek it, which is great.
