"For example in dac... Dac is a mature technology, and we can now afford a very good one at relatively low price..."
See, this is where the comment breaks down. You can get a very good measuring one, but it may not sound that good. However ASR minions will argue that all Dacs that measure the same sound the same. Rubbish! ESS based Dacs sound shrill in the mid range. Also what is this "mature technology"? Over the years technology tends to improve. Despite your name, (though the Latin is magister), you are not much of a teacher.
I have already said Amir is rude and intolerant. A number of posters have already been banned from ASR for posting contrary opinions, yet Amir is here posting his.
As far as Amir’s measurements being incorrect or off beam, there is plenty of information around on the web, you just need to look for it. Just one example is the silly testing methodology of the Chord M Scaler. Read the following if you want more examples.https://audiophilestyle.com/forums/topic/65677-why-you-cant-trust-measurements/#comments
If you want more, look at some of Amir’s headphone reviews and then read the following:

Then you get people like Matt Hooper, who is actually one of the members of ASR who has less of an attack dog mentality, and who posts under the name "Prof" here, though heaven knows what sort of Prof he is, who post nonsense like "The thing is his critics will never cut him slack." Well "Prof" if you come to erroneous conclusions or use poor methodology why should you get cut slack?
