Great find. I've been looking for something like this for awhile now. I thought about the microcube, but at only 2 watts, just seemed a little too mineature. I can't find the power specs on this, but if it is running 2 speakers instead of 1, somehow it must be putting out more than 2 watts. I only found one really crappy video of it; the demonstrator had no clue. Need to wait for a couple more demos and some more specific specs. But a light-weight amp with battery power and the cosm technology seems like a really nice little practice amp and something to just be able to take anywhere, parties, jam sessions, etc.
