So purrin completes the triumvirate: FR, CSD, HD. Well done sir! If I might only indulge upon you to add a THD line.

*raises hand*

Sir, I still don't quite understand what to make of the graphs. Or rather, the y-axis and how that relates with frequency range.

P.S., do I need to reintroduce myself in the appropriate section?

Since these charts are log based I would like see the 0.5 tick between each major interval.

Looking nearer at the charts I see each line as I should have noticed before....now I can see it.

Well done!

What does the 6k spike on the O2 2nd harmonic translate to in listening?

Just means that a 6kHz tone will result in another 12kHz tone (2nd harmonic) about -24db down. I checked the CSD - no ringing at 12kHz. Probably benign because it's high up and just in a narrow area.
