I want to use my sound card's (X-Fi Fatal1ty Pro) DAC and connect it to a headphone amp (Fiio E09K, no DAC, only amp).
The sound card has line out and spdif out ports. Which port of the card should I use? What is the difference?
The amp has pre out, line out and aux in (RCA). Which one of these should I use? What is the difference?
I know I can use a 3.5mm to 2xRCA cable to connect line out to line out. What other combinations are possible and which is the best for what I want?
