It looks like I'm leaning toward the Aune. I'm reading good things about it on multiple threads, except for the power supply which requires a bulky adapter. I'm sure I can get a replacement one for US outlets though, so it's no issue. The amp is supposed to be very good, just like devast above said. And I have not heard of any blowing up, doing a sudden death, or frying the cans on your head! 
My only question is that since the Aune doesn't have an on/off switch, how do you turn it "off"?

It also has good quality pcb in it, thick and sturdy(unlike the zero). Also i just checked the sellers page, he's saying: "Sorry, out of stock now.
