12/20/2016 UPDATE: http://www.superbestaudiofriends.or...ux-and-quick-impressions.60/page-2#post-94971 I'm a little bit late on this, but several months ago, OJ mentioned to me that I should definitely give latest new iteration a try. The jist of it was that Alex (of Audio Zenith) managed to get rid of a most of the PM-1/2's distortion characteristics. I was like whatever, BS. Well I'll have to eat my words on that one. I'll steal what Hands described as the "the neutral, generally easy-going tone" at Tyll's Big Sound. Those of you who have spoken to Alex knows that he places the highest priority on frequency response; and I believe that he has accomplished his goal. These are among the most neutral or flat sounding headphones out there with the least tonal issues. One area outside of frequency response where the PMx2 excelled was with transient response and separation in the treble. This can be easily heard with distinct hi-hat techniques where the separation of hits is distinguished rather than the bled together as heard in traditional dynamics. (Although I still feel the best dynamics resolve better.) I tried this headphone with the EC ZD Super (with a high 20 ohm output impedance, which is not optimal for this 32ohm headphone) and amazingly, the PMx2 didn't have too much of an issue with softness, probably because of the PMx2's super sensitivity. However, I felt the PMx2 was most at home being powered by the Ragnarok, where its extra power, especially into low impedance loads, offered a more slam, articulation, and sustain in the bass. There's nothing much else to say, mainly because there is nothing wrong with it. Measurements are forthcoming.
