I built my computer with a Gigabyte GT board with a DAC UP discreet USB ports, it will be my source to my Maverick D2 DAC (shipping from China soon). One of the few DACs I found with 2 outputs.
One SS output will go to my Emotiva Bass X A100 desktop amp, the D2 has a tube for the second output which will go to my Dark Voice 336se headphone amp.
Now all I need t complete the setup are the 6xx !
