With a week off I foolishly decided to start measuring things with my new RME ADI-2 pro ADC/DAC. This included the turntable setup. I used a HFNRR test record (plus an old mono test record). I got consistent results in that L channel response drooped a bit at high frequencies and crosstalk was very difficult to optimise despite fiddling with azimuth. This was using two different carts (mm and mc) and two different preamps.
I used the HFNRR pink noise tracks for response as well as the mono disc for some distortion measurements. Distortion -40dBc at best, -25dBc at high frequencies or levels above 0dBr.
Not sure how to explain the differences. It is a unipivot tonearm, so that could be a problem.
An example shows the channel differences. I have eq'ed the rig flat using the RME so assuming the test record is OK I am happy.
