Measurements?
Hard to find.
Only Kef's and this FR plot from Polish magazine Hi-Fi Voice:


Measurements?
Imaging is one of those epiphenomenal characteristics of speakers. If a speaker measures well, then it is likely to image well.
I've found that imaging and frequency response are not necessarily related - its more important that the left and right speakers have as close to identical responses as possible and that includes influence from the room which should be symmetrical. I've deliberately equalized response, and have run, say, the HF driver only with no real impact on imaging. But asymmetrical room influence plays havoc with imaging, as does differences in frequency response and relative phase between the left and right speakers. Having the speakers as far as possible from wall boundaries is important.Creating a phantom center image for example is not rocket science, it's basic (psycho)acoustics. I posit that a speaker could test rather less than well in say, FR on axis, but still 'image' quite well. Even two quite mediocre L/R speakers can do it well, if placed correctly. The EQ of the image may not be 'accurate' but the image itself between the speakers can be as 'solid' as one would hope.

The vertical plane of the HF and LF drivers in my system is adjustable, and a fraction of an inch can make a relatively large difference in response at the listening position at the crossover region. This effects imaging to a degree, which is why I go to the trouble of getting it right.
As a lover and owner of a few mechanical watches, I completely agree.Tubes are just like mechanical watches in that you are making a choice to use old technology for fun, even though there is cheaper solid state technology with better objective performance. The only difference is some people think tubes actually sound better. I don't think they are better, but I think mine sound just fine. Mine probably color the sound far less than the best passive speakers, though I I don't really know as I have never seen measurements.
Someday I will get around to making a test load and see how they actually perform.
I have wondered about some of Dynaudio's design decisions. The Dynaudio Consequence (their former flagship) is one of the strangest speakers I've ever laid eyes on. Another one that I have seen but not heard, sadly...

The picture does not provide a good sense how huuuuuuuuge it is.

Reinforcing the idea that loudspeaker 'imaging' is essentially about speaker pair location relative to listener location. Even the room can be factored out if desired, by listening in the near field. Or by going multichannel, where you are getting direct 'imaging' cues that overwhelm reflection cues.
If your left and right speakers are for some reason significantly unmatched in output, which I doubt ever happens in real life except when something is broken, then possibly that would mess up imaging, skewing it to one side. I also remember well how often 'center' imaging with vinyl playback was skewed left or right, but that's one of the many reason not to bother with vinyl in this day and age. It's a flaw in either the LP or the TT/cart setup, not something to do with the loudspeakers.
It does point at your shinbones. Something about time alignment, blah blah blah.Wow! Is the speaker 5 metres tall, or does the tweeter point at your shinbones?
