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.

Great post!

 

But  many people dont figure out generally even the difference and correlation between acoustic science and psycho-acoustic...

We are like RCA dog thinking the voice come from the device itself not  from the room/ears...

I could go on for pages and pages more, but the end point is that physical measurements as they stand, connected solely to engineering criteria and weighting, fail to take into consideration the capacities of the human ear and brain and generally fail to understand ’hard engineering based measurements’ limits and limited scope, in application, to the complex question at hand.

 

I think Amir is excellent and had an ideal methodology. I wouldn’t buy anything that didn’t pass muster with him. ASR is an outstanding site. But, if you like million dollar cables and hyped up rubbish it isn’t the place for you.

Great topic. I too agree it can take a long time to really appreciate & understand what a certain component is doing or how it sounds. Often, once you get used to that new sound, it becomes our new standard & how we think it "should"sound.  It's a strange phenomena. 

That said, comparing speakers in the same system doesn't take very long & to me, usually sound quite different. This can be due to the amp driving them or the room & set up & the synergy between it all & the speakers so it too is not a for certain thing what is creating the differences, but they are usually very clear.

You opposed here "measuring tool fetichist" against "listening brand name gear fetichist"...

They have the same ignorance in common with the RCA dog listening the pavilion of a gramophone with NO ROOM between his device and his ears...At least the dog trust his ears not a decibel meter or a spectroscope only...

These two groups put acoustic and psycho-acoustic way behind their obsession with the gear in their journey , but it is , unbeknownst to them alike, MAINLY with acoustic treatment and control  we can  reach reach optimal sound/musical experience with a speaker/room ...

Measuring is useful...Listening is useful too and correlating the two in acoustic is mandatory and the only fundamental for explaining sound experience... For sure the most deluded are those who trust more a tool at the END than their own ears...

Acousticians use their EARS to tune a room...Guess why?
