What was nice about Tyll's work, was that he was subjective in his preferences but also pretty much spot on in consistency with his assessments, thanks to measurements, but also for sticking to a meaningful concept of what could be perceived as neutral sounding. So it was easy for one that followed his work, to figure out how much weight Tyll's criticism carried in regard to one's, perhaps different, subjective preference.
Basically, if a reviewer doesn't have a consistent subjective sound preference, and, or, is unable to portray it clearly and meaningfully to the readers, the resulting reviews are gonna be useless, either because of lack of critical information and, or, the readers not being able to gauge where their subjective preferences fall in relation to the reviewer's impressions.
Basically one's reviews can be consistent and meaningful even without measurements, well, as long as they are consistent and meaningful that is. Good luck with that.
