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.

your ears need to burn into the sound as well. Its no different than anything else that is new in your life. It takes a period of time to adjust to it. If you buy a pair of shoes they wont feel right until they have burned in. Part of this is the rubber becoming softer as you continue to wear them in. Of course eventuallly, the shoes will wear out which is a different thing. 

I never heard them say that the lighting would look better after the wires burned in

That is because the efffect would be too subtle to see. However audiophiles care about the smallest differences they can hear so that is why burn in cannot be ignored. 

More importantly, custom tuning is compulsory. If you want your speakers to suit your ears they will need to be tuned to your ears, and not the designers ears. 

We have to test the product to see how good it really is. Its not a question of enjoyment. Its a question of TRUTH. If you dont care about how accurately your system can reproduce the signals you put in then you are in the wrong hobby. A speaker should not be enjoyable it should be neutral. The enjoyment should come from the music itself not the equipment. 

Here is an example of the good work the folks at Audio science review group do for the community. About a year ago, a speaker company known as GR research perpetrated a hoax on the audio community and came out with a cheap little speaker which they called a Little giant killer. It was essentially a cheap wooden box with a single small cheap driver in ’em. The simplest speaker you could possibly have.

News got out and eventually ASR decided to get their hands on them and test them. The results were shockingly bad and the hoax had been exposed.

 

 

It is work like this which the audiophile community needs. ASR are the unsung heroes of the audio community.

 When folks with those claims are tested formally, they cannot repeat their outcomes.  

The problem is some audible effects are very very small but still important. These differences would not be detected with a traditional blind test. The knowledge that you are being tested would be enough to counteract your ability to hear the difference as it shifts your focus towards the test rather than the music. This is why the double blind tests are wrong. We would need MRI scans to really understand if certain effects are audible or not. If you do 2 seconds of jitter could you hear it? yes of course we can. But once you get down to the picosecond range, a traditional blind test will not be adequate. 

For the record, I don’t equate the positive measurements you found to an expectation that I will enjoy its sound, in my system, in my room, with my ears, and with my brain….  How great it would be if it were that easy - I truly wish it was!

Why bother measuring things if it doesnt equate with sound quality?

But my own subjective experiences in HiFi have given me enough of a glimpse to firmly believe that there is more that we don’t know.

Arent you just contradicting yourself? You just said we dont know what we dont know. So perhaps we have all possible measurements or perhaps we dont. You cant then claim that your subjective experience gives you a firm belief that theres more that we are not able to measure. Your subjective experience might also just be imagined. Perhaps that $5000 cable is useless after all?
