RightMark Audio Analyzer loopback quality - 16-bit/44.1kHz
Next, we have a series of "loopback" tests that run the front-channel output through the line input, giving us a sense of overall signal quality. We'll use CD-quality audio again for this round.

In our first loopback tests, the Xonar DX takes the top honors. The Xonar DGX and DSX look evenly matched and better than the Realtek audio overall.
Before you flick that scroll wheel, check out the Xonar DGX in the frequency response plot. Again, it starts dropping at lower frequencies than the competition. Also worth noting: the higher noise and distortion exhibited by the integrated audio in several of the graphs.
