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.

Good luck with that!. ASR often doesn't bother listening at all to some of the components it tests. It just isn't important to them if they have their measurements to review. I think looking at numbers is more fun to them.

Amir has claimed that he personally listened to "200" pieces of equipment per years.  That is around 366/200 or 1.5 days per equipment.  I mean come on who in the world can take you seriously if you only spend such a short time evaluating an equipment.

In comparison, people at Stereophile spend weeks on an particular equipment before they publish the review.

You seem to be backtracking now from your previous claim which was:

 

"Why then SS amp ALWAYS has a haze where as tube amps always has a transparent sound "

(emphasis mine)

There is no evidence you’ve given to support this. The last SS amp I had in my system to compare to my CJ tube amps was a Bryston 4B3 and there was no "haze" that you mention to that amp, nor to any other SS amp I’ve ever heard.

And if anything it is more transparent than the average tube amp (which can include many expensive tube amps - see Stereophile measurements).

Whether we are talking about beginner audiophiles or audiophiles who have managed to acquire top end gear, it’s still the case solid state generally seems more popular and I see no consensus at all on this "haze."

A lot of audiophiles project and generalize their own impressions as some form of "truth" which makes these conversations a bit fraught.

 

prof,

If I remember correctly, you had stated you could not hear any difference in cables.  If that is the case, I am not sure I can take your words seriously.
