I've got some photos of it up on flickr, so check the link in my sig, and full impressions up at TouchMyApps forums. I have no idea if I'll review this amp/DAC more than I have already. This unit is an engineering sample from MyST on loan from Dimitri Trush. It looks and feels the part, but is very interesting as its inputs are many, its battery capacity, huge, and its functionality very good. The DAC is the 16bit AD1866, which many or all of you know of, that operates only 44,1/16bit, but the 1866 DAC receiver chip allows for 24/96kHz playback without hiccup with all but Bluetooth input. The sound is thick, powerful, with good volume pot balance and low noise. It has a low pass filter pretty steady in the upper frequencies, hence a sound somewhat like the Hifiman series. People whose thing is the Hifiman will love this as packed next to an iPhone or iPod touch or other playback device that offers CD-level music integration will mean that you get NO gaps, and no playback hiccups, and you can keep the amp in your pocket while reading books on your iPhone, or whatever you like. Indeed, while BT may sound silly to audiophiles, and there IS some signal degradation VS optical, it is very useful, and sounds wonderful. The engineering sample as its antenna placed somewhere under the front plate, so gratuitous touching will cause the signal to cut in and out. Bugger. But, this is an engineering sample. The full version is supposed to have a proper antenna. I think I'm here to say: you may want to rethink your stance on BT. I've used it for hours and hours in the past three days and can recommend its idea. If it pans out, it will be a wonderful (and expensive) DAC/amp for users IEMs, headphones, computers, iDevices, smartphones, and in between stuff.
