I use the iDAC2 only as a DAC for my HP amp plugged like:
PC -> generic USB cable (taken from ASUS Xonar U7 usb sound card which I use at work) -> iPurifier -> iDAC2 -> stock RCA cable (from iDAC2) -> Littledot MK2 -> Beyers T1.2.
Since I need a longer cable I plan to buy a better one. I took a look at QED Reference and QED Performance. We will see if these make an improvement.
At the moment I do not plan to add other iFi stuff like the power source or Gemini to my setup... too expensive and useless for me, since my other 2 DACs have their own powersource and cables.
