@Robbo99999:
Sorry, I just don't like to fullqoute. That's why I choose snippets and reply to that, but also answer in context to the rest of the post which I think needs further commentary. That does not mean that I disagree with points that have not been mentioned btw. Take the 'high base THD = less clean when boosted to Harman' or 'high Q sounding worse than lower Q' aspects as an example.
Like already explained, there is nothing wrong with experience that shows certain correlations between measurements and practical listening per se. All I was trying to say is that you should not judge the whole thing without actual listening, just relying on sheer data or 3rd party experiences like you wrapped it up in post #5 or #54.
Saying that a headphone has no potential because it oscillates in the upper frequencies is just pure measurement bias without any profound pratical verification. As you probably know the plots themselves are always compositions that mix driver, cup and ear resonance together. All of that can change with seating and individual geometry. Resonances may or may not occur and change by manipulating those variables. Narrow peaks that appear in the plot (induced by the interaction between the driver, cup and ear) may or may not be an audible issue in practice because we are not talking about a fixed curve. Then there is psychoacoustic smoothing (masking) due to the dynamic filtering of our brain. So why should I take such a plot as sort of evidence that could
replace my personal listening experience?
What I am trying to say is that the experience with your four samples is not neccessarily wrong. It is just too optimistic to take that as a holistic rule that can be applied with high certainty to every other headphone you are only reviewing by looking at someone's measurements.
If you don't trust me, listen to Solderdude's words at least who certainly has a lot of experience in both measuring and listening to headphones.
We should be very careful with the tendency to self-affirmation and -justification of such techniques. That's what ASR is often being accused for.
