I am definitely interested in these. I have and use everyday the em5813, and I adore the sound of them. The bulky cable is a complete PITA, and they are heavy, but of all the IEMs I have gone through the sound of them keeps me engaged and fatigue free. They are not the most comfortable, but the sound is. I run these out of my RWAK100s with amp, and they need no EQ (yeah I know my source is old, but it sounds good!). If these are near the same sound sig, I am in big time. With the Audeze LCD-2/3/X, I have to EQ the AK to get the sound I want, but with the Cardas em5813, I use no EQ and the sound is simply spot on for me. These look to be for me. I have spent so much on IEMs and the cardas do it for me. I guess I have strange tastes considering how so many people think they are rolled off, or dark, or lack detail...I can kind of see where that perception comes from, but I just simply enjoy the music when I use them. That's what it's all about, isn't it? Any news on these coming out? Are they available yet?
