I don't mean to be a downer but has anyone read about the batteries that Neco is using on these... From Amazon reviews, the ultrafire 3.7 V seem to be kind of unstable. Of course, I'm a worry wart. It seems like having the dual mono set up would lead to channel imbalance if one of the batteries started losing juice quicker than the other.
I still wish there were an external gain switch.
Very relevant questions, Isaiah.. if you don't follow up with Neco on them, I will.
