Trust me, disillusion, tests are done in fairly controlled manner (they're controlled beyond your imagination or anything you've doubted

If you mean the Golden Ears measurement http://en.goldenears.net/10680, I'm sorry to tell you that they have only measured the 80ohm version. There were two other graphs provided by donunus showing the 'difference' between the 250ohm and 80ohm one but the source and methodology is unknown. Next time you might want to check your sources before you say things like "trust me".
If you want a good source, maybe you can send both the 80ohms and 250ohms to Tyll of Innerfidelity for measurements that are made under more controlled circumstances.
Things are relative, as you might want to insist, but never really flat. Irony is that strong advocate of democracy (e.g. let's respect variety of opinions) tend to discriminate those who hold something against it. In other words,
"the people who claim that they are the same/mildly different/vastly different all have about the same credit to me"
to me means "please forgive me avoiding risk to make judgment about it (just now)", which I think is perfectly normal and valid perspective. And, as you may already know, such perspective doesn't discount the fact that some people here participate in building something out of sharing experience with the aim of limiting possible conclusion about 80 vs. 250 ohm difference, even if that "something" was far from perfect.
If you want to take it like that, feel free to do so. I have already decided what I would do should I want to order these headphones. I just mean that people should make their own minds up regardless of other people's opinions (or just takes people's claims as opinions not fact). Since the information is not perfect nor complete, different people can look at the same info and come to different conclusions logically, just like stock analysts looking at a company's report and coming up with different buy/sell ratings.
Unable to recognize the difference between 80 and 250 ohm ver. of dt250 is really no longer a matter of opinion at this point. It's only about amount/depth of learning to listen to music through both dt250s. Frankly speaking, one doesn't know/cannot tell the difference because of ignorance. So it's perfectly normal for those who don't own dt250s to ask owners about them. It's just strange when non-owners -based off of their belief-systems alone- try to disprove us owners experiential opinions.
Yes it is a matter of opinion still. When you are dealing with sensory systems and how the brain interprets the signals, there is a significant of variation among people and how they perceive things. Some people taste things when they hear a sound (just google synesthesia). Some people call a colour green whilst others call it blue. There is still a lot of debate between what is audible and not (even when there is measurable difference), and the methods used to test these hypotheses, you just need to visit the sound science forum to see it. Perception is not perfectly translatable between people. If person A hears the difference, it doesn't mean person B will do too. And vice versa.
Real question is, how much does the 80-250 ohm difference means to each one of us personally? and not if there's any differences.
I don't agree with your assumption that everyone will hear the differences. Neither of us currently can prove or disprove this assumption, because we don't have the means to test it out on enough people to make a good sample size. Actually I just need one negative sample point to conclude that your experience does not translate to everyone, which is already provided earlier.
Why don't you find that out yourself, since all we dt250 owners can do is to offer "opinions" others can endlessly doubt? I just remembered that there's some quote, too, in this thread, from Beyerdynamic engineer to explain the difference between 80 and 250 ohms.
Yes I think it is an opinion you offered, but I do not endlessly doubt you because there is no need to. I just don't think your experience will necessarily translate to me. I base my decisions on what is practical for me - which is cheaper? which is easier to get? etc. But I don't think there need to be anymore debate between us because you have decided they are different and I have decided that I don't care. I am writing such a long reply because I think I am contributing too - by telling others that it is really just mostly opinions here, and suggesting people who cannot decide to take a step back and consider other pros and cons, and not focus too much on the differences.
