So the next round of testing was performed...

I began with the XONO, with my main aim being to correct the THD+N v. amplitude graphs from the previous tests. This time, the measurement was taken with standardized values for the input voltages (200 uV - 1mV for MC, and 600-5mV for MM) and capacitive loading (100 ohms for MC, and 47 kohms for MM).

This THD+N (MC) looks a lot more like the XONO factory pic. I think my error in the previous one was that the reference voltage wasn't corrected...the range here was 10 uV - 10mV.

This is THD+N vs. frequency for the MC input.


Frequency response for the XONO MC input.
and the phase response.

Finally crosstalk.

The Moving Magnet response was pretty much similar. Below are screenshots of these graphs.

This is the correct THD+N for the MM input. The range is 600 uV - 250 mV. Looks like the factory pic.


The THD+N vs. frequency for the MC input looks just like the MC input.

as does the frequency response...

and phase response.

The cross-talk is a bit different though. The values are about 10 dB lower in the MM.

IMD and idle channel noise for both the MC and MM inputs can be seen in the previous posts with screenshots. Next up tomorrow is the Steelhead.
