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.

Deludedaudiophile, good luck with your battery venture.  You might want to learn more about metrology.  You can take some courses or learn more from the ISO or MIL Q Specs about test equipment certification and traceability.  These are industry standards and plenty of calibration labs around the country to get your test equipment calibrated and certified for a reasonable cost.  Turnaround times are pretty quick if no repairs are needed.

Who do you think you are fooling? Do you think people referencing 35 year defunct organizations like they still exist are taken seriously by anyone but the deluded? You need to get with reality bud no one buying your story. Throwing ISO or MIL into a sentence does not mean you know anything. If anything that you don’t reference specific standards shows you are just attempting to grandstand in the hopes someone will believe you. Those are not  standards. One is a standards body, the is just some letters. Mil spec standards are across a range of entities.

P.s. the battery venture is doing fine, it’s a good business to be in, lab budget almost unlimited but tied to profitability. Only small companies send their stuff out for calibration. The equipment we have that can be calibrated is done on site. But you wouldn’t know that.

 

 

 

 

deluded audiophile, your behavior- argumentative, disrespectful of others, spending 5 seconds reading about something on the internet and thinking you are an expert, indicates that you are a young adult living in your mom's basement somewhere who has accomplished nothing.  Step away from the keyboard and go outside and play.  The sunshine will do you good.

Bud, you referenced a 35 year defunct organization and didn’t even know it ... 35 years. ANYONE with actual working experience dealing with anything related to calibration and standards would not have done that. Just who do you think you are fooling? Again you referenced an organization defunct for 35 years. Not one or 2 years, 35 years. You are not fooling anyone.

 

PS the important acronyms and items of interest are NIST/ NVLAP, A2LA, IAS who are members/adhere to ILAC/APLAC so their results are accepted anywhere, and ISO/IEC 17025 defining their operation. Most of our equipment can only be calibrated by the manufacturer most of which have been certified by one of those bodies listed above.
