I also admire the 1000ZE/X, having used it on more modest arms--a Jelco, and a mildly modified Thorens TP13A. The things that struck me first about its performance were its speedy bass, macro-dynamics, and neutral/beautiful midrange tone. A terrific music-maker but I agree with you about its initial imaging skills. I didn't fully break in the NOS stylus, I'm certain.
If you have an owners manual on the cartridge you've probably noticed that it recommends a widget that I presume had been enclosed with the cartridge, to hold the cartridge a bit nose-down in its mount (from parallel to the arm). Presumably to make VTA adjustments easier with most arms. I don't have the widget.
Not having the widget and not wanting to fabricate one right now I decided to leave further experiments for another day. Waiting for it's place back, in my case instead of your Nagaoka, was an Empire 600LAC...
I know this doesn't directly address your questions, but perhaps someone else will dive in?
