Sonorworks reviewed these in 2019 so this review isn't saying what is already knownDT770’s were my first real headphones, these results don’t surprise me, but I will always have a soft spot for them.

Therefore, I fail to see any reason for you to add the claim that this headphone needs to be connected to an amplifier with very low output impedance.
Your own site shows that the dt 880 600 ohm ( lower than senn 650) has at least ok distortion ( the dt 990 pro has no distortion measurement) ... its looks and sounds way more positive than you sound over here....All those Beyers are limited in max. excursions.
The very early (high impedance ones) even had zener diodes in anti-series to prevent maximum excursions.
Later on Beyer realized this was a bad idea when connecting it to a power amp.
Mount Beyer ... some like it, some don't.
All Beyers are equally 'flawed' when they are driven to points they weren't designed for.
114dB = their maximum continuous power rating (100mW)

Measure them again after a few months of use.

you're right. The holy Trinity of the old big three was always k701/2, Hd600/50 and dt 880. Depending on taste. The dt 990 was never part of it. At least here in Germany.I always thought the 'trinity' was K702, HD600 and DT880.
I tried all three years ago (see avatar pic) and kept the K702.

It must be restructed by location. I see an embedded video.black picture? ......
Seems like dt880 sales are not on par with dt990you're right. The holy Trinity of the old big three was always k701/2, Hd600/50 and dt 880. Depending on taste. The dt 990 was never part of it. At least here in Germany.
Amazon wasn't even really around back then as much as it is today (over here) ... don't see what one seller in the USA proves against my point.Seems like dt880 sales are not on par with dt990
That fr target is the subjective / preference Harman targetThese reviews are strengthening my belief that headphone-phile is just a mess of subjectivity with no link to objective performance. The $9 Sony has less deviation from target.
In the American studio in the 90's it was the 701's,600's,and the 990'syou're right. The holy Trinity of the old big three was always k701/2, Hd600/50 and dt 880. Depending on taste. The dt 990 was never part of it. At least here in Germany.

And choosing to not go for one subjective target curve, but instead going for another subjective target which has a similar shape but shifted right by roughly one octave, if that isn't subjective designing, I don't know what is.
But I guess the users get to say "Oooo lots of details and controlled bass"
