Yes, this is true.

One big problem is that when you're trying to discern differences on
the threshold of perception then it's almost impossible not to be
influenced by expectation. The only sure way to avoid this is to get
somebody to help you to do blind testing. If you know which audio
component is being tested, then your perception is biased.

I'm aware of opamp theory and I understand why some engineers
think there's no reason to "sonically evaluate" opamps. However,
I have my reasons for doing so and if anyone thinks me a fool for
doing so, so be it. They ain't got'ta be so arrogant and snobbish
about it however.

Sorry about that, but we've seen too many people whose "knowledge" of
high quality audio consists of pseudoscience, mystique and
psychobabble rather than good science, engineering and psychology. The
requirement for op-amps with flat open-loop gain is based firmly on
pseudoscience so that's why you've not been received well here.
