Hi, I am intending to get a DAC for my desktop rig (PC Source) that has both Coaxial and USB input. I have my sights set on the Fiio e17 (so when I upgrade in the future I could just include it in my portable setup as well). The Fiio e17 has a SPDIF, Coaxial and USB input, but I was wondering
 If I could use a 3.5mm to Coaxial wire into my PC headphone jack and to my DAC to bypass my onboard DAC.
 Could I use a 3.5mm to RCA (red and white), by plugging in one of the RCA connectors into the DAC, and still get stereo sound?
My current concerns are:
1. 3.5mm to Coaxial wire only transmits analog signal, not digital
2. Headphone jack output of my PC does not bypass the soundcard's DAC
As for why I do not want to use USB?
1. I want to expand my options
2. USB input is limited to 24/96, whereas Coaxial input goes up to 24/192
Any constructive input is appreciated!
