Hi audionewbi,
 
Yes 004 is yours.
 
let see more to come on the 2nd batch, first off all let see the complete measurement and calculation on out impedance and power deliver. we are waiting for another tools to come by today to complete measurement, just to make sure.
 
if you can you can measure by your own tool.. we are please.
 
after all casing set up, will be hearing test by a few of our friend, the result will be post here.
