Did you measure the pink noise SPL above the TT?Acoustic feedback effect on turntable ...
I put a stationary record on the TT and lowered the stylus onto it. I then play Pink noise from the speakers, while recording the cartridge/pick-up signal. This is what I get
Turntable 1 Michell Gyro SE, SME V AT-OC9MLii at 59db gain /200 ohm. No platter mat used,

Then another TT Denon 51F with Shure V15 IV Jico SAS-B at 39db gain /47k added to the plot=blue curves

Getting the Lab version, it's two records and it has more features.There are two version of the record, standard and lab. they have e good video explaining the content. Looking forward you your review
Haven't found a dealer, from the website of Unitra - that ships the WT-2 or any products from them for that matter, to the US.Seems it does not have sweeps for L and R, only L+R.
I totally agree, and didn't mean to clog up the topic. I just don't know if there are problems or not.(It is just a courtesy to the thread starter and the purpose of this thread to keep this thread as much as possible as a "database". But of course - the more cartridges measured the better, so it is welcome! But if there are problems that needs to be sorted out, keep it as a new thread or in the Fun... thread)
All the settings are the same (win and 2i2). I even tried different drivers. At 48 and 96 the graph is the same, but offset within 1dB in places.I have seen such problems when using Focusite. Is is extremely easy to mess with the setup, you may think you are recording at 96k but PC is doing it at 48 or the opposite. You have setting in the sound card/ the interface , PC , and recording software for xxkhz , that all have to match. The problem is in the recording process it self so looking at the file may not help. Try to toggle “Allow exclusive control” in sound settings and see if it makes a difference. Try to record everything at 48k , an then 96 again.
Look at the spectrum for the 1khz pilot tone in Your recoding software, REW , or Audacity if you are desperate .?is it at 1khz?
Can you use something else than Focusrite Scarlet as an PC interface?My Solo was so erratic that I gave up using it…it turned out it was the “exclusive mode” in PC sound settings the cause a lot if problems, still do not trust it fully
What kind of cable are you using?My tonearm (Moerch) specifies 28 pF for the internal tonearm wire - then I have ≈100 pF for the RCA cable, and add 10 pF for the phono stage connectors getting around 140 pF. The results I get are quite consistent with that figure.
Did Korf specify (measured) values for the tonearm? You should also be adding 10-15 pF for the phono pre. It is never "zero", and can vary some depending on the connectors and the PCB layout.
