1. No it's a noise file.Is the distortion in that video harmonic distortion?
Did you test in a way the video said you should not test?
Were your results sighted or blind?
Is there any reason to think that your calculations might not be valid?
2. Not sure what the video said about how to do the test. I don't think it matters since I'm not trying to prove to anyone, it's just for my information. Basically I've come to the conclusion that I can only realistically hear harmonic distortion around ~-30dB maybe -40dB at best, so that corresponds to a distortion of about 1~10%. My ER4SR has less than 0.5% THD both sides so I don't think I'm gonna hear any distortion soon.
3. Like I said, it's sighted, then with closed eyes. I won't bother to set up an ABX / blind test when I already have the conclusion I was looking for myself.
4. What does it matter. All I need to know is if there's any chance I'm going to realistically hear ~1% harmonic distortion and the answer is no, even if I could it's not significant at that kind of volume where I have to:
1. know what I'm looking for
2. ignore the music and go searching for artifacts.
I don't listen to music that way. So it doesn't matter as long as the THD is not above ~1-2%.
