Mr Trev
Headphoneus Supremus
I think the rest of you guys might have to wait for the official release on the Fiio site. Mr. Trev indicated that the stock FW isn't able to be uploaded straight from the unit. I'm not sure how these things work though, so you might have to ask him about it.
I have no knowledge bout this, but I just meant that I don't think there is a way to dump the firmware off an already flashed device. I assume this means the rest of us are: 1, SOL until Fiio releases the new version (I'd bet a pair of Skullcandy Titans it won't be until after the X1 goes on sale.) or 2, buy a new unit.
As far as some of the earlier posts go.... Big Rock Traditional Ale does improve the X3's sound quality.
