It is interesting that the second-harmonic in the 1kHz distortion measurement is higher than the third-harmonic. Seems to fit what Tyll said in his post a few pages back. Quoting him:
"For example, if the distortion is even-order, it will be much less disturbing than if it is odd-order."
Has anyone who has a PM-1 tried it with tube amplification?

I think it's more than that, specific to the case of the Oppo PM1.
There is a stigma around a "newcomer" headphone brand that according to early impressions are literally the best thing ever, crushing the established top headphones. If you put yourself in the shoes of HD800 or LCD2 etc owners who visit this thread and see people discussing how PM1s are better, you'll quickly see why people are wary and/or defensive.
The real problem is that people are basing their opinion on measurements without having a clue what those measurements mean. I can look at those graphs and know exactly what to expect. But most people don't know what a dB is or which frequencies are important and which aren't.

You give our little corner of the web too much credit. I see people on HeadFi making mountains out of molehills every single day in every single thread. There is more knowledge of specs than there is understanding of the context specs fit within. People think that inaudible frequencies are important and distortion lower than the lowest sound floor in a quiet library is significant. How many dB variation from flat is still flat? Very few seem to know. The thresholds of human perceptiion are never applied to these graphs except in the most extreme cases.
I agree with bigshot. I have been in Headfi for a few years already and I have been into Hi-Fi equipment for over 30 years and I do not have a clue on how to interpret those frequency charts and to be honest I don't care to know because we hear different, we interpret things different and we have different tastes. A headphone could be technically perfect and produce a perfect frequency response chart but maybe I am too sensitive to certain frequencies and I might not like it. That does not mean it is not perfect or not good. It just means it is not for me. That is why IMO there is nothing better than listen and experience it yourself to make a comment or decision which still is relative to you only.
Well here is another spec that most people here aren't aware of... For people with normal human hearing (not damaged), sound is pretty much the same for everyone. I've seen charts that measure the sensitivity to specific frequencies on multiple people, and they don't vary more than 4 or 5dB. Listening to music, a difference like that would be barely noticeable.
Good sound is good sound. If something has a flat response, low distortion, a low noise floor and a wide dynamic range, it's high fidelity sound and it will sound natural to everyone.
