Understood. But why the downward tilt at ~17 KHz. Your plots (granted, of the103R variant) show the rising high end I would have expected to find).
Follow Ups:
Look again. My plots are also tilted down after 17-kHz. They start to rise after 7-kHz, but they begin to roll off after 17-kHz. Their massive cantilever and stylus places their cantilever bending resonance around 17-kHz and they roll off after that.

Here is a comparison of the massive DL-103R stylus and cantilever compared to the lower-mass stylus/cantilever system of the DL-S1. Both pictures were taken with the same magnification.

The flattest frequency response curve I ever measured was from the Dynavector XV-1. It was flat from 20-Hz to 20-kHz ±1-dB.
There's no correlation between your plot of the 103R and the one that came with my 103. No rise after 7 KHz. No rise period.
I've never measured a DL-103. I've only measured a DL-103R and a DL-103SA. I've never used a chart recorder and a sweep frequency test record to measure frequency response. My measurements were made from RIAA equalized spot frequencies through my phono stage whereas the plot supplied with your cartridge was made with a constant velocity sweep without RIAA equalization. Therefore, you are correct: There is no correlation between my measurements and the plot supplied with your cartridge.
My measurements reveal how my DL-103R performs in my system through my Pass Labs XOno phono stage. Your plot was done in a laboratory without RIAA equalization and therefore does not show how the cartridge performs in your system. That is the main reason I make my own frequency response and crosstalk measurements -- so I know how all my cartridges perform in my own stereo system.

Those ruler-flat charts that come with (some) cartridges are silly and pointless. Nothing to do with you or your charts. Believe it or not, this isn't about you.
"this isn't about you"
I suggest that would be more obvious were you to make an effort to not come off as such a miserable snot.
How you could post that nasty comment about one of the nicest guys here is beyond me.

As the saying goes, takes one to know one :-)Are we having fun yet
I'd probably come off as more warm and cuddly but i'm watching the World Series and just checking in between innings.
