Though fast processors and killer graphics cards may attract much of the attention and hype in the PC industry, I would argue that audio is one of the more unappreciated components out there, though it's probably the second most important sense we use. The discrete audio card is probably the greatest unsung hero, as it were.

Although probably best known for manufacturing top notch motherboards and graphics cards, ASUS also produces a line of audio cards as well.  And if their success in other product markets is any indication, we have high expectations of their audio lineup as well. But today marks a bit of a departure from the premium, flagship products we normally see from ASUS. Instead, we're looking at their entry-level sound card, the Xonar DS PCI 7.1, a rather diminutive card which promises to bring some great value to consumers with modest budgets.

Let's take a close look at the ASUS Xonar DS and listen to what it can do for an affordable card.
