I have the Zx2, P1 and KPE's as well. I have to admit, I'm not really hearing what I understand you are hearing. In my view, the P1 are good, but they can't quite match the KPE.
If I don't adjust the volume while changing between the P1 and KPE, the sound is a bit too loud on the KPE for me, but I don't detect any distortion (if that is what you heard). As I hear it the KPE have noticeably better clarity and a bit more detail. Overall, they also sound more natural. That is not to say that the P1 are not good out of the ZX2, it's just that the KPE sound better to me. I tested the P1 both with normal trs cable and trrs cable, with basically the same results. The volume didn't really make much of a difference as the P1 are relatively hard to drive and I find the KPE benefit from a bit more power. Listening to both, I would describe the P1 as a less clear and detailed version of the KPE. I find the sound signatures of both surprisingly similar. I am using spiral dot tips on the P1 and Symbio W peeled tips on the KPE.
That is very interesting.
Do you have the EU version of the ZX2? I understand that the EU version is greatly limited in output voltage due to some (stupid, excuse me!) EU regulations.
Yes, the P1 are really hard to drive and I need the Mojo to drive them to louder levels, max volume out of ZX2 is moderate at best. But at that low volume I actually preferred the P1 over the KPE (adjusted to roughly the same volume)
On the Mojo and at higher listening levels, I fully agree with you about the KPE being clearer and more natural sounding, although I sometimes feel that that particular combination can almost be too smooth.
