ASUS Xonar DX PCI Express 7.1 Audio Card
Performance Analysis: Overall, the ASUS Xonar DX's performance was very good, often rivaling that of the premium class Xonar D2 Ultra. The vital statistics reported in RightMark Audio Analyzer 6 show the Xonar DX to offer significant improvements over a quality integrated solution, while coming extremely close to the quality of the Xonar D2 Ultra. In gaming, both Xonar cards offered slight improvement in framerates, but it's the enhanced audio qualities that are more evident, with excellent spatial orientation in game as well as with DVDs.
With the Xonar DX PCI Express 7.1 Audio card, ASUS aimed to deliver a more affordable upgrade to integrated audio than previous offerings, while providing an experience that rivals more expensive audio card options. We'd say ASUS has definitely attained that goal with the Xonar DX. The Xonar DX delivers significant improvements over integrated audio, inregards to both features and quality. We were quite impressed with the overall performance of the Xonar DX and in several instances could not distinguish the audio quality from that of the pricier Xonar D2 Ultra.
For around $90, those looking for a better PC audio experience versus integrated solutions should look to the Xonar DX as a significant upgrade. Considering how closely the Xonar DX rivals the Xonar D2 Ultra, which sells for nearly double the price, the Xonar DX also looks to be a respectable value. The ASUS Xonar DX is a solid product, well suited to gamers and HTPC users alike.
