Wow, just listening to the demo unit I got today. Headamp is a Questyle CMA 600i and source a Lector Strumenti CDP 707 - which is nothing less than a match in heaven. Especially with EDM, which I have never experienced that natural, liquid and organic. If those cans weren't that heavy I would like to dance with them.
Bass has an absolute fantastic authority and slam while it is perfectly defined, slightly elastic and fast. Something special has to be mentioned about the translucent texture of the bass. Sounds to me like there is a third dimension HEDD invented. In opposition the mids come up light, fluid and beautifully transparent, which for me is a fascinating pairing with the strong bass. The mids presentation is simply effortless, nothing screams for attention - everything is just there and pearls out easily. Treble shows great resolution and finest microdetails but doesn't bother me at all although I am absolutely treble sensitive.
Soundstage: did someone say they sound closed in? For me they are wide open, at least partially. Some instruments and effects appear and dissappear out of and into the deep and wide nowhere while others are located directly in your head. Still everything seems perfectly integrated into the whole presentation, the stage seems endless. Lots of air between the instruments! Again I feel no planar or dynamic headphone has ever shown this variability in depth but I agree to those who say the heddphone appears like a cyborg that grabs the best from all technologys. Simply amazing - I am just listening to Scubas "Claustrophobia" for the second row and still cannot believe what my ears are getting to know, really holding my breath not to miss any detail.
The overall signature for me is full and rich in texture and also, sorry for that, kind of futuristic. Never have enjoyed my music that much!
