I got a Microstreamer a few weeks ago. So in case anyone still cares, I'll chime in.
I spent a while yesterday comparing its DAC to that of the Pico, using the Pico amp in both cases. It seems to present as much a sense of depth as the Pico does. The sound is different though. For now, I can't say which one is more accurate. I'd probably have to compare both to my Lavry DA10 to figure that out, and I'm currently too lazy to do so.
The software controlled amp works as they claim. There's a little delay after you hit the volume key on your phone, tablet, or computer, then the volume changes. There's also a line out, which is a good thing for me.
Unfortunately, the amp only has one gain setting, which is way too high for IEMs. With the Roxannes, which are efficient even for IEMs, the Microstreamer amp is unlistenable. The noise floor is terrible. I can't really fault HRT for this though. They have to build to a common denominator. The first thing half the fools on Head-Fi do when they get new portables is plug their HD800s in. At the very least, there's an expectation that LCD-2s will have sufficient gain. I wrote HRT and asked them if there was a firmware modification to drop the gain. Unfortunately, they sent me a link to an attenuator cable.
The DAC is the stand out. I'm impressed with it thus far. The sample rate indicator is nice too. But it's all of very limited use because of the amp's high gain and associated noise.
