Downunder, i have own most of the list you suggested :)
I have a P3a not P3, the biggest different between the two is the tonearm. The P3 tonearm use rubber decouple for the counterweight shaft, overtime time it may sag a bit, just like my P10. It also lack the active resonator absorber on the arm tube. The P3a arm on the other hand use rigid couple on the conterweight shaft. The armtube is different and equip with the active resonator absorber. With P3a arm you get a very low distortion and direct lively sound. You should hunt for the arm to realize the full potential of this TT. They are truly superb....
