ASUS Xonar DX Sound Card

The Xonar DX is capable of delivering 35 times cleaner audio quality with 116dB SNR in comparison to most motherboard onboard audio with only 85dB SNR. While noise is unavoidable, the Xonar DX dramatically reduces the amount of background noise, and it is this distinction that allows the Xonar DX to produce as little as 1/32 (-105dB) of the total harmonics distortion versus traditional motherboard audio (-75dB).
