Interesting... I actually had a chance to listen to the Dharma yesterday at Jaben, Singapore. I'm not sure if it's a pre-production demo unit. With regard to sibilant trebles, I only found it occasionally. But that I put down to the bad recording of the pop song that was one of the demo tracks. It sounded fine with the Eagles and other music I played. Of course, it undoubtedly needs burn in to take the edge off some of the hard edges. While it's a nice can, it's not compelling at this stage. I'll revisit once it has been burned in. What I will say is that the HD800 type socket was too recessed and will be difficult to remove cables. I had a heart stopping moment with the crystal piccolino balanced cable from my HD800. Which brings me to the next issue I had: the OEM HD800 cable doesn't do it any favours: the same cable that can make the HD800 sound poor is used here too. Once I swapped it out in favour of the crystal cable, the treble was more rounded and calmer while the mids filled out and the vocals not so recessed. And the bass kicked in. The last observation is that earpads are poor. Too thin and were not the most comfortable around. Looked like some cheap OEM earpads from any shop selling supplies. While the idea behind the can is good, I think in implementation these chaps are letting their good work on the Drivers and concept down by having these cheap and perhaps not well thought out parts. Just my thoughts.
