Is there a Peter Principle of Audio…

A Peter Principle as it applies to audiophiles and their quest to continually upgrade?

We all have different levels of abilities to perceive and appreciate differences in audio equipment and music. In some cases it is due to physical limitations with hearing or just a lack of musical appreciation or the ability to “listen” to music and perceive subtle differences. While the Peter Principle is about people rising to their level of incompetence in their work, that word is not be the best word to use in an audio context. But the principle still  applies where one reaches a level where they can no longer perceive any incremental audio benefit from upgrading.

There is a lot of information about the “best” equipment, interconnects, room treatments etc. but rarely do I ever read an honest discussion about individual limitations to perceive differences at the higher levels of audio equipment. I think there should be more awareness on this subject because it IS important in making individual system decisions.
