#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?
