LOL - it wasn’t amp burn-in/ed, it was You!
@westcoastaudiophile you have your opinion and you are entitled to it. But you DO NOT know what I experienced. Yeah it is not measurable YET - similar to how hundreds of year ago, people were not able to prove that the earth was not flat THEN. As science progressed the truth was revealed.
Please do not tell me that humans have reached the pinnacle of audio measurements.
