Not that Amir is always right or every conclusion and argument is unimpeachable.
But..he has a hell of a lot of knowledge and experience, and many of the criticisms that from sites like this come from audiophiles who "don’t know what they don’t know." In other words, they project their own ignorance about measurements and the science of psychoacoustics on to ASR and Amir. "Measurements don’t tell us x or science hasn’t determined Y..." are often statements of personal ignorance, not actual knowledge of the engineering or science itself.
Anyway, somewhat along those lines...
ASR emphasizes how it measures and not how it sounds, which is missing the subjective musicality in the equation. I would encourage their members to go to concerts and recitals and listen to more live music and well recorded and well interpreted music as these are important dimensions beyond test measurements. Don’t just test the car, but look out the window and enjoy the journey it takes you on.
That’s a very common mischaracterization. For one thing, that ASR just cares about measurements not how things sound. That’s ridiculous. The whole POINT of caring about the measurements has to do with how things sound! Amir is appealing to plenty of good engineering and science which correlates measurements to how things sound! So for instance once you have distortion measured at certain levels, it’s beyond our capability to detect. Likewise power and impedance measurements of speakers and amplifiers can help put in to context the possible sonic consequences of various pairings.
And of course frequency responses for speakers relate to how they sound. Look at a B&W frequency response and if you know something about correlating the measurements to sonics, you’ll have some idea of how they will sound, especially the upper frequency emphasis. Many people who say "you can’t tell a speaker’s sound from the measurements" are mostly talking about themselves. Just because they haven’t learned the correlations doesn’t mean other people haven’t and don’t find speaker measurements informative about possible sonic issues.
And Amir appeals to some well established science in terms of how certain suites of measurements predicting speaker sound quality and preference ratings - see the research done by Floyd Toole and others. So this idea that it’s "just about the measurements not how things sound" is frankly just ignorant.
Now, though I’m an ASR member I don’t think the ASR approach is the only one for enjoying the hobby or choosing gear. I personally am usually curious about how something measures but, especially with loudspeakers, I always have to listen and go with what I perceive. But on the other hand there is no reason whatsoever to disparage an educated audiophile for buying gear based on measurements. If they know what type of performance they are seeking that’s perfectly fine, and it’s clear many on ASR and elsewhere have had success with that approach too!
