if i use the e17's SPDIF input function by sending 24/192 signal from my soundcard, am i still using Fiio e17's onboard DAC? or am i using the soundcard's DAC. i think i kind of know the answer to this question, but i just want you guys to confirm this for me.
Yes, sending a lpcm signal from your soundcard into the E17 through S/PDIF uses your E17's DAC.
Its a digital signal, meaning it has NOT been processed by the DAC
Think of it this way, the DAC is the digital to analog converter, if it has even touched or went through your soundcards Digital-To-Analog converter, it would be an analog signal comming out of which SONY PHILLIPS DIGITAL INTERCONNECT Format would not be able to use it. Only AUX in of the E17 can use it. If it's AUX in, you are NOT using the E17's DAC.
