Hi all, This is my first post but I have been reading the site for quite awhile and finally decided to purchase an Alpha DAC. Since I am not in US and my local dealer only has one demo unit left, I want to check what is the current firmware version of Alpha DAC. When I turn on the unit, it shows "Alpha 0.70". Is this the most recent version or an upgrade is required? Thanks for the helps. DC
