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.

It is the reason why i called them : measuring tools fetichist...

There is also the brand name tasting fetichist group...

The two groups underestimate and dont give a damn about acoustic...the most powerful known upgrade is acoustic and psycho-acoustic devices...

Don’t you think it is a bit strange that someone would buy a equipment just to "test" it and not listen to it?

 

" the manufacturer is not willing to foot the expense of well conducted, objectively fair listening tests to support their claim "

What is measured? Sinad? Look up how useful sinad is and you will see that it is not that useful.

Actually- this thread was not about electronic measurements.  It was about Amir’s observation about the human brain and its ability to hear non-existent improvements when switching components because we start listening in an “analytical mode” when we are testing hifi equipment. Of course, Amir is not an expert in psycho acoustics, but I thought it was an interesting concept and many members related to it to some degree. The human sensory system is so easily fooled. Ever take one of those flight simulator rides at Disney?  Vibrate the seat, tilt it back and show us a video of flying and we swear we are traveling through space. A little scary how easily our senses can be deceived. What do we do with this knowledge?  Whatever you want, that’s what.

SINAD is useful but it's not the only thing measured. It seems to me the amount of half truths and downright nonsense posted here about ASR borders on paranoia. Perhaps it's because they are a growing presence and some feel threatened but after all it's just another website the deals with measurements and objective and to some degree subject aspects of high fidelity playback systems. You dont have to take everything presented there as gospel but with an open mind you might surprise yourself as to what you might learn.
