measurements are important and that’s without a doubt. But alone, the measurements cant tell you how a component will sound or what sonic changes a cable can make.
Yes actually it can. Measurements really can tell you what you won't hear in a cable. Amir showed how the measured signal of the Nordost lined right up with that of a cheap cable. That tells you they will be audibly indistinguishable (in any likely set up).
You apparently reject this because you believe whatever you think you hear. That's the problem.
It's no doubt the same problem that lead you to claim:
Testing Nordost Tyr 2 on a Topping DAC driving a Topping amp using headphones won’t tell you much for few reasons - Topping components aren’t high end by any means
On what basis do you conclude the Topping is not "high end?" What do you think that means? Amir actually has measurements showing the excellent performance of the Topping, with noise below our hearing threshold.
It's not "high end" in being expensive...but you shouldn't judge gear based on price, but on performance! And not on manufacturer's claims either. Amir actually tests manufacturers claims.
And if you simply reject the objective evidence Amir provides because your "ears" tell you, after listening to the Topping, it's not "high end" then that just brings us back to my point: it's the Golden Ear refrain. "I Know What I Hear...measurements be damned."
It's not actually unfalsifiable, because you COULD put what you think you hear to blind test controlling for bias. But most audiophiles won't do that, so in their world "what they perceive" is unfalsifiable. Just like my claim to hear angels on the Miles Davis record. And since I won't be blind tested, and I reject the primacy of measurements, well...nobody can prove me wrong.
