Why HiFi Gear Measurements Are Misleading (yes ASR talking to you…)


About 25 years ago I was inside a large room with an A-frame ceiling and large skylights, during the Perseid Meteor Shower that happens every August. This one time was like no other, for two reasons: 1) There were large, red, fragmenting streaks multiple times a minute with illuminated smoke trails, and 2) I could hear them.

Yes, each meteor produced a sizzling sound, like the sound of a frying pan.

Amazed, I Googled this phenomena and found that many people reported hearing this same sizzling sound associated with meteors streaking across the sky. In response, scientists and astrophysicists said it was all in our heads. That, it was totally impossible. Why? Because of the distance between the meteor and the observer. Physics does not allow sound to travel fast enough to hear the sound at the same time that the meteor streaks across the sky. Case closed.

ASR would have agreed with this sound reasoning based in elementary science.

Fast forward a few decades. The scientists were wrong. Turns out, the sound was caused by radiation emitted by the meteors, traveling at the speed of light, and interacting with metallic objects near the observer, even if the observer is indoors. Producing a sizzling sound. This was actually recorded audibly by researchers along with the recording of the radiation. You can look this up easily and listen to the recordings.

Takeaway - trust your senses! Science doesn’t always measure the right things, in the right ways, to fully explain what we are sensing. Therefore your sensory input comes first. You can try to figure out the science later.

I’m not trying to start an argument or make people upset. Just sharing an experience that reinforces my personal way of thinking. Others of course are free to trust the science over their senses. I know this bothers some but I really couldn’t be bothered by that. The folks at ASR are smart people too.

Decades ago Peter Walker of Quad did a listening test of two amps

I have to completely agree with you here. Science and mankind have not made any progress since then. You should be given the Nobel award for this find.

I am puzzled as to why anyone thinks a "blind" listening test should require a blindfold.  "Blind" means that the test subjectl/istener does not know which equipment is being used - not that the test subject/listener is blindfolded.  

 

Measurements and specifications are important, but they don't necessarily reveal how something will sound. I find Stereophiles measurements essential in helping me evaluate equipment and company's products! What's bothersome is how misleading some companies advertised specifications are. A recent speaker review in Stereophile found that the speakers sensitivity ratings were almost 8 dB lower than what the company specified! Even worse are power ratings for tube amps. It seems the new standards for company's power ratings are at 10% distortion! I've even seen a review discover an manufacturers mistake in one piece of gear. They were putting in a lower gain modules from a cheaper model product in the more expensive product and the review alerted them of the mistake!

As far as ASR goes:

There was a time that Amir, on many posts, would post a photo of Pink Panther asking for site donations to keep the site running.

In a thread here, not long ago, he said he has +$200,000 worth of testing equipment.

"Suddenly" becomes a chi-fi proponent?

Could have come from donations.

Just as likely it didn't.

I'm on the side of it didn't.

 

 

You cannot tell if you will like driving or owning a car from measurements of its performance.
