Firstly I do very much agree with the fundamental idea of the seven levels of audio perception, but my view on them is slightly different.

Also, it is not up to the listener to select the depth of the levels listens.
This implies that it is up to the stereo equipment to determine the perception and perhaps there can be one ideal stereo system. While it is consistent with what is observed, it means that there is no human variation in listening (unlike what has been demonstrated for all other human senses) and means that many people very interested in audio perversely prefer stereo systems they know sound bad. It is a difficult position to defend.

The lower levels act as blocking mechanism for higher levels, not truly blocking but rather as “power consumption” levels and that “consumption” eats out listening strength.
Have you never been in a mood where a song comes on the car stereo which moves you greatly emotionally? Yet it is despite the very poor quality of the audio reproduction.

The definition of success at each level could be determined ONLY by how far the success was reached at the NEXT level.
This says that the seven levels are linked (i.e., an effect on the the 1st level will impact the 4th, etc.) so that it implies errors on the static level must by definition affect the other levels.

It is impossible to have “improvement” at lower levels but at the same time to have a negative impact at higher levels.
It is like saying you can not have a better frequency response but a worse transient response simultaneously. I do not buy it. I would suggest that all types of listening may potentially be mutually exclusive: static, dynamic, emotive, etc.
