Is ASR for real, or is it only for those sub $1k or even sub $2K?

Acoustics already is a very complex field rooted in objective measures  about perceptions and their physical external modifications parameters, it is also rooted with psycho-acoustics in subjective perceptions for themselves taken seriously as a field of study in itself (speech,music,).

The division between subjectivist and objectivist (ASR) is ridiculous but the more ridiculous is the one cult who by partial educated ignorance claim to eliminate hearing subjectivity  from the acoustics equation instead of training it and who use the Fourier tools whose limits of application  in psycho-acoustics context they dont understand . (Milind Kunchur points and Van Maanen points )

Acoustics can be complicated but not necessarily complex. A complexity theory approach would involve more than just acoustics.

You are right because you think about some applied acoustics  for room or great Hall ...

When i spoke about acoustics what interested me is  hearing theory not just applied material acoustic but psycho-acoustics theory and application for speech,sound and music.. This is complex because multi-disciplinary and a mystery till today ...

I think we’re on the same page here. My argument is that there is a complex interaction between music, gear and listener in an environment.

Measurement of a single component may be helpful in that it specifies a necessary condition for success. However, it is very far from a sufficient condition that can reliably predict outcomes for the whole complex system.
