@douglas_schroeder What exactly are you saying? I am quite confused.
You say that you do hear changes and break-in, as said from post above.
But you also said there is no such thing as break-in or changes, they all sound identical. Even amplifier warming up is a myth, and that your test is the only thing reliable. Not the hearing.
But you are using your hearing to test. So let’s be clear about 2 things
1) Hearing is not reliable.
2) Your test involve ears.
Am I understanding? I hope I'm not understanding because I am not.
