Of course, Id love to share some. Right now, I am having my ZMF verite Silver cable re-terminated to DCA connectors and then will do some serious listening and A/B'ing. From what i can tell from my brief listening, these are really different from ZMF cans. Zmf cans have THE most natural timbre that i have ever heard. PERIOD. ZMF headphones sound natural. Plain and simple. Especailly with an OTL amp: that combination is just hard to beat. But thats not why i bought the Expanse.Looks like you have quite the ZMF stable, I (and surely others) would love to hear ZMF related impressions and comparisons.
Full disclosure, I traded for the Expanse. Of all the planar headphone i currently own (including the recently traded LCD-5), the he1000se and the Expanse are two of the most unique sound. The hifiman is airy, sparkly with details for days, accompanied buy a soundstage that is both vertical as well as horizontal. The Expanse takes on similar properties of the HeKse but adds tons and tons of depth with extremely clean, dynamic sound signature. Its very detailed, i guess i would compare it closely to the hifiman but the expanse throws you in the middle of the stage while the Hifiman presents the music in front of you. There are better instrument separation with the Expanse compared to the ZMFs, and I think being detail heavy sound signature definitely contributes to that. The Expanse does instrument separation better than both ZMF (Atrium, VC) and Hifiman HEKse. However, the instruments sound more organic and natural on the ZMFs. Vocals are a toss up between the Expanse and ZMF. Male vocals have more weight with the ZMF, while female vocals have more transparency and crispness on the Expanse. I am not yet sure about my feelings towards the Expanse bass. Going to listen to some hiphop/gangsta rap lol and check how the Expanse handles the low end.
Overall I am really happy with the Expanse. Much like most other DCA headphones, it is unique. It does certain things exceptionally well, while competing with TOTL headphones in other aspects of the sound.
