The A-Vortexbox can be powered by a seperate 12vdc linear ps. SGC sells one of those for that purpose, also the SOTM USB card is designed to clean up the power supply "noise" on the USB cable and can be powered with a separate linear ps. Another cool feature on the SOTM card is a switch to send data only to your USB dac if the USB receiver is internally powered.
I use the Dspeaker Anti Mode Dual Core and the data only feature would work well with it.
