ASUS Xonar D2 Ultra Fidelity 7.1 PCI Sound Card

Introduction and Specification

Claiming to be the best at anything is bold.  From professional athletes to product manufacturers, stating you or your product is the best out there opens things up for closer scrutiny.  Being the best at what you do, or what you make, means near flawless execution.  Regardless of the context, one thing is certain, if you claim you are the best at what you do, you better be prepared to back those statements up.  This is the position ASUS has put themselves in, stating that their latest product is the best of its kind, period.

In this HotHardware showcase we're going to take a look at a new sound card from ASUS called the Xonar D2 Ultra Fidelity 7.1 PCI Surround card.  Although this is the first sound card ASUS has delivered to market, they've come right out stating they feel this is the best sound card currently available.  That's a confident statement, especially considering this is their first sound card release, not to mention the current state of integrated solutions that can rival the performance of some of the best add-in cards out there from the likes of Creative and others.  With that said, we're going to take a complete look at the Xonar D2 Ultra Fidelity 7.1 PCI Surround Card to see if it really is the best of its kind or if ASUS' claims falls short.
