I got an iDSD today and have been using it with my Noble Audio Katana CIEMs. I'm liking it enough that I think I'm going to sell my Hugo 2. I'm not saying it's better than the Chord, but it is different and really good. I don't need anything portable and after a few hours listening to the tube output on the iDSD, I definitely like it. I am having 1 issue, though. I am using the Onkyo HF player on my iPhone with the apple camera accessory and then USB from that to the iDSD. My phone is constantly "losing" the iDSD. If I pause a track, the phone doesn't see the iDSD anymore. Unplugging the usb and plugging it back in does nothing. I have to turn the iDSD off and then back on to get the phone to see it again. Is this a known issue?
