Also your saying you removed the 15volt output options that is found on other card for the headphone output because it would ask to much juice from the usb but what if it's plug in the wall??? Most people that will buy the card will plug it in the wall and not use usb power (since it bring usb electrical noise and everything).
It would not have been very complicated just to give the option but explain to people that 15volt option is only working with external power!! + a way to bypass the headphone out totally for external headphone amp..
I have to admit that this card seems to be the one to buy even at 749$
but that low power headphone output is really bugging me since i'm interested in 250ohm to 600ohm headphones.
