Amir has been doing this for a while. And has a standard procedure etc. And knows what he is doing. If he had to re-explain every facet and the significance/reason for each test at every review, it would be far too cumbersome. He does not need to write a 40 page paper for every amp tested.
Anyway, how detailed do you want? Either you have high expertise in the field of audio measurement so as to understand even more highly technical details, or you don’t and they won’t help much.
