Hey there,
 
I want to improve my stereo sound on my HTPC (Realtek 889A), right now it connected to my receiver (Yamaha RX-V3900) via HDMI (ATI 5450).
My setup: Focal 816v fronts, cc800v center, REL R-528 subwoofer and DIY rears.
 
So before I purchase a DAC, I'd like to try a decent soundcard first.
 
The options are:
AudioTrack HD2
Asus Xonar Essence ST \ X
 
The AudioTrack is the cheapest.
 
Is any option worth considering?
 
Thanks.
