Unfortunately, the Pocketrak preamp has a high self-noise level (lots of background hiss), in comparison with other recorders at the $350 price point. So it's not the first choice if you're trying to make high quality recordings of live music.
There's a point where a recorder becomes too small to easily operate its controls. I think the Pocketrak is a good example of this, at least for my fingers. I could work the controls only by taking it out and looking at it. That's not good if you're looking for a stealth unit.
