That has nothing to do with the discussion of a statement from someone (ridiculously) saying in this thread that HD580 was basically the same headphone as an HD650 - the differences are large enough that it's not explained by any small revisions, it's totally absurd to even think otherwise. Also I think it's established that there are not significant differences between any of these potential revisions - I think Oratory once said that any changes fall within unit to unit variation, he doesn't distinguish any difference of revisions of HD600 or HD650 in his measurements. Your snippet of information you present is not related to the conversation that was being had, and certainly it is of no proof that you can say "actually both sides have their correct points". Poor post from you I'm afraid, I think you have an axe to grind with me based on an exchange we had way back when, so I intuitively know you act to cast doubt on my posts. You should have better standards (& of logic/discussion rigour), you normally do in your daily posting of which I'm not involved.The problem is that there is not THE HD600 but it had several changes over its production years, so actually both sides can have their correct points:

How do you know if Oratory has measured all models, for example also many HD580 models and also very early HD600 ones? Also when measuring them as you know there is also the big influence of the worn state the pads are. Actually even the over years changed pads from Sennheiser have quite an influence https://diyaudioheaven.wordpress.com/headphones/measurements/brands-s-se/hd650/ My point is just that what he said for example that if ordering spare parts for them from Sennheiser giving you the same driver nowadays can be true and also that the heard differences (which depend also alot on the pad version and condition and the deep bass content of the music) can be very small, that's all, what you interpreted to them seems rather your own problem when I see the remaining part of your above post.
That shown pad wear effect is not as large as the difference seen in the Oratory measurements between the two headphones; that point aside, see the following....
Exactly, the question had been raised often in the past for example in German forums where the HD models were always very popular and quite few people had similar impressions.
It is sad that it took so much effort, but glad to hear they eventually honored their commitment.
Absolutely.
In the bass region? Given the huge preamp difference measured by Oratory (-14.5 dB vs. -5.5 dB, that's 9 dB difference), I doubt that any HD
My bad, there was a typo in my post (I wrote once 590 instead of 580). But we have been discussing of the 580 and 580 was written elsewhere in my post, so it should be obvious that I was talking about the 580.

It's OK, it's only because you didn't read everything:
In other words, it's a disaster in the bass region when compared to the Harman target.
The problem is that if you look at Crinacle's measurements of HD580 then it's really quite close to an HD650, so we're already talking about a large difference to what Oratory measured for the HD580 in the bass. So it definitely seem that there's at least some HD580's out there that are very similar to HD650/HD600. Graphs in the following post:
