… of course you have….
Thank you, can you do the same test but with tracks 9 and 10 to see the drop in frequency response closer to the center?Azimuth did change slightly between takes. Also, this copy is slightly warped. Side A up at the edges, side B down.

My 3 Clearaudio CA TRS-1007 compared@mackat very nice results. Interestingly in your measurements we don't see the the azimuth related crosstalk problem. I wonder if different issues of that test record behave differently in this respect? I will pay more attention to the side of the test record next time...
I have noticed in this thread that in many cases you get very different crosstalk graphs from left to right and right to left. To make it more difficult to assess if the problem is in the test record or cartridge installation, results seem to vary from system to system and also between test records. In my measurement, crosstalk was and is quite different between channels and the same happened with Jico SAS as well as the original needle. The cartridge is visually installed straight and I don't believe both of the needles would have an azimuth issue. Of course it could be the cartridge coil placement that might be the root cause in my case.Thank you! Which crosstalk problem are you referring to? I tried to adjust azimuth visually as best I could with these, and I think I got pretty lucky.
Sure, I will try to get to that soon.Thank you, can you do the same test but with tracks 9 and 10 to see the drop in frequency response closer to the center?
How did you measure "Phase" ?Another AT-VM95ML:

Thorens TPU 257 AT-3600 Re-done with different turntable Sony PS-212 and changed lower input capacitance on modded Puffin RIAA .NISTE suspect Antikating was too low on thisThorens TPU 257 = Audio-Technica AT3600= Rega Carbon

NOTE Bought this to the to check/ eliminate if some strange vibrations on low noise spectrum can from my MC cart or not, turned out to be a vibrating belt causing the anomali.
- Cartridge: Thorens TPU 257=Audio-Technica AT3600=Rega Carbon
- Stylus condition new <5 hrs on vinyl,
- Test record: ClearAudio TRS-1007 side A track 1&2 L/R stereo
- Turntable and arm: Michell Gyro SE. Measured peak wow <0.1%. Arm resonance with cart __Hz
- Tracking force: 3g
- Phono stage and loading settings: Parks Audio Puffin. EQ=500R-0=corrects for TRS-1007 and B&Q QR2010/QR2009 response. Toslink out to USB converter to PC
- Capacitance and impedance: 50pF fixed, 47k ohm . Total 147pF with cables
- SUT if used: Not used
- Cable capacitance
- Try to measure if you can, it matters with MM cartridges: 15+80+2=97pF internal arm leads, cable, connector) +50pF RIAA
- Multimeters tend to exaggerate this, LCR meters work best and are a very useful tool to have: Vendor statements
- ADC: internal in Puffin.
- Recording: no adjustment on balance, no Azimuth adjustment on cartridge, 5-48kHz, PC and Puffin at 48kHz.
Yep. Jico should do better with this one.That's reaching for the sky.
IIRC, all the V15V SAS are a miss. At some point I'll have to measure mine - I have B/Z/S/R versions. I think different loading may help you, though. @Thomas_A and I remembering right that you've tamed the B?Yep. Jico should do better with this one.
You did show more linear response after reducing R though. In another thread.Yep. Jico should do better with this one.
