Only briefly. Concensus from a few people I trust is that the WM1Z2 doesn't quite hit the level of sonic refinement that the WM1Z does. Specifcally it seems the OG 1Z has more of a bass tilt whereas the 1ZM2 is a little brighter and upper mid focused. I can't verify this though.
I heard it briefly once early on and found it too bright. My sense at the time is that it was a little overhyped. Time seems to be confirming that suspicion.
I preferred the Lp6 just slightly to the N30. It was just a little bit smoother and the bass a bit tighter. I prefer the 1Z to both, however, which may be a controversial opinion. Sony & Cayin really knocked it out of the park with their WM1Z and N8 players, neither which have been properly bested even now imho.
