#1  Speakers and amps need to be made synergistically.

Why "made"? Why not just matched?

#3. High End audio companies rarely show scientific measurements. Why not?
 
Would they guide people? Why? My sense is that most do not know what to do with them, and those who think they do often overestimate single data points.
 
#4  Audiophiles have very little knowledge of music production.

Why is this relevant? I don't know much about food production, either, but I'm capable of tasting, grading, discriminating what I eat. 

#6  Snake oil is not loathed but treated as an amusing possibility for better sound.

I've never seen an adequate definition of snake oil. Do you have one?

#7  Expensive equipment, confirmation bias, ego, no standards, will eat people who don’t like expensive cables.

Why is this bad?

#10 Audiophiles make subjective decisions claiming to be scientifically objective.

Isn't it a scientific fact that they subjectively preferred X over Y? Not sure what you're getting at.

#9  Audiophiles are always moving toward a goal.

Is a circle a goal?

Hilde45 +1 😊

#8 Very little blind listening tests.

I made many simple blind tests in my few years of mechanical, electrical and acoustical incremental process of optimization for my system ...

Then you means by blind test : double blind test protocol ... guess why it is generally useless for me and any other audiophile optimizing his system ?😁

Only objectivist fanatic promote double blind test as the only "proof" of a small change ...

For small change i dont need public validated proof because all ears, all designs and all gear pieces and all acoustic rooms or all headphones etc are not equals ...

For big change i dont need double blind test public validated proof either ... A company may need it to sell it , not me designing my own system with gear pieces i use my ears.. ...
