No point in using a soundcard if your going to use its digital out; the equipment at the other end of the audio chain and not the soundcard will be driving the audio quality.
No there is a big diference...
I got a Realtek Digital-out on my mobo and a Creative X-Fi Titanium digital-out and i can hear the difference
And the Creative X-Fi Titanium got a bunch of tweak options
So i wonder if the Asus Thunderbolt got better tweak options than Creative X-Fi Titanium?
