I think one has to separate out Amir’s approach from some diatribe one receives from others on that website.
To be fair to Amir: he has never recommended a measurements-only approach. If anything, he espouses that (properly conducted, level-matched) listening tests are more important. It is just that they are difficult to conduct for a casual listener in the manner he suggests.
He does weed out badly constructed snake oil in many occasions.
However, after studying electronics engineering for 4 years and later working in a ‘measurements and calculations are everything’ world for a few decades, I still feel that they are necessary but not sufficient.
ASR asks to prove it. As a hobbyist who likes to listen to music to relax, I’m not interested in the effort.
I can make out differences between *certain* speaker cables though they measure identically (with our current measurement set), for example. Or, prefer the Holo May DAC to the beater measuring Topping D90SE.
