Soundcard as a pasthrough for my USB DAC?

post #1 of 12
Thread Starter 
Am I better off using my DAC separately via USB or connect the DAC to my Soundcard (Xonar D2X) via Coaxial? If better off separate, think I will sell my Xonar as I really need the front volume control.


Will be connecting my AudioEngine A2's on these..

Technically there should be no difference as both are sending a digital signal. I would try both and see if you can make out any differences.

I would go with coaxial. It won't sound better, but you will still get the nifty Xonar features.

He won't even be getting all of those nifty features. One big reason to use a sound card's digital out would be for uncompressed 5.1 audio.

I would just use USB personally.

ok you got a outside Dac. So it won't matter. But for gaming you still want the sound card for the cans. so do you have a sound card currently?
If not the Xonar DG ($30) coupled with the MK5 ($5 - 10) IF you don't wanna switch inside windows between them if your not bothered about that you can ignore the MK5.

Im pretty sure there's a way you can make the Xonar act as a transport/passthrough in bit-matched mode since alot of onboard solutions support this. This should give the same quality as USB and allow you to use DSP features when gaming/movie viewing or off when you play music.

The other way around this is to have both the Coax and USB plugged in and just switch playback devices accordingly (i.e. USB audio for music, Xonar for the rest).

Actually, my Headphone amp is not USB. I connected it to my Xonar via Digital Coaxial. How would I connect my A2's to my amp so I can have front volume control? My A2's and amp only have Aux-in connections.


Amp:





AudioEngine A2:





I tried connecting my A2 speaker wires to my amp, and it wouldn't work..so, right now I have my A2's connected via Aux on my soundcard, and my headphones on my amp..I have to switch the inputs everytime in windows, which is a pain
