The graphs are updated without SUT. Results are basically in agreement with spec ±1 dB for X40 and +2/-1 for Verismo.

On SHF I see configuration B 30db gain is used. Even if X40 is 6ohms the B config compromise both top and bottom end using the ST-70 SUT, time to try config A ? that would also show the SUT capability. The B config is not impressive here

Ortofon MC X40
New when measured.
Does not meet the specs, especially so for the cross-talk. I did not try to dial it in due to the performance.

Ortofon MC X20
New when measured. I don't like the sound of the cart. Partly because of the resonances @2-3kHz. I did not try to dial it in due to the performance.

They seem to be ≈ ±1 dB, which is spec. And distortion seems low. I have hardly seen better measured MCs from Ortofon.
Latest pic look awfully like Ortofon's fine line stylus (on the x-30). Odd.

OK, I should have written "spec" for X40, i.e. the cross-talk.
Do you mean the last X20 picture? Ref "Latest pic look awfully like Ortofon's fine line stylus (on the x-30). Odd."
the elliptical they use is an ogura like the fine line but the fine line has a longer contact patch. dont they usually look pretty similar?
Shure V15 type iii mr
picked up a vn35mr stylus being sold as lightly used/basically new. looks as advertised under the scope. my v15 type iii body is mounted in a v15rs cap so it can accept a wider variety of styli. so much for flat. you think a ton more capacitance would flatten this out? the highest setting on the art pre is 200pf plus the 80pf of the cables.
before i found my type iii body, i tested this stylus in my v15v that's mounted on my sl-1600 mk2 connected to a puffin. not much of a difference

Audio Technica at155lc
picked this up because old reviews i read said it tested fairly neutral. not this sample. it was pretty much any other AT 4 coil cart. diamond looked close to new. i moved this one on and am keeping/using the ml150 and ml170 along with the 540 body with 40ml and 45xml styli.

Damn. For some reason I thought the III would’ve done a lot better. Any signs that the elastomer is hardening?
I think I have a 155LC, so maybe someday we can compare.

Perhaps it is so. I tried to look for good nude pictures of the Ortofon
but failed.

This stylus is clearly broken or your measurement chain has problems, see all the results for V15III MR cartridges/styli posted before. Units sold as basically new most probably are everything but. Honestly, for me is difficult to understand why somebody feels the need to publish uncertain measurements of styli grabbed in the garbage within a reference library thread.
I take the point, but it can be useful to have record of how a particular stylus can degrade. That has always existed in this thread, as you can see at the bottom of the index. It would be beneficial that the measurement post clearly and prominently states it's an abnormal sample once an issue is identified and confirmed.
or how about you go search through all of my posts and go check out all of the different carts ive measured before assuming my measurement chain has problems.
with a very unscientific finger wiggle test, it feels just as supple to movement in every direction as my currently in use vn5mr. i tried that with a vn5he with a hardened suspension and the cantilever broke down at the magnet. this performs as well as my vn5mr's and new audio technica styli on the 300hz tracks of the hifi news record. if there's anything else you suggest looking for, im willing to try it.

The main issue is that throughout this thread we have dozens of measurements of the same cartridges: Shure, Shure Jico, AT, AT95, etc., and it doesn't seem to elicit any reaction... What I find is that once a few different samples of the same cartridge have been observed... especially with non-NOS cartridges, available new, a small Excel spreadsheet with "cumulative capacitance" values, or even impedance, could be recommended in a more conservative manner than the often "generous" manufacturer recommendations... ;-)
