Introduction

We all know them, our one friend who is completely obsessed with their PC's audio performance. They generally spend hundreds on the top of the line sound cards, the best studio quality head phones, and a completely absurd amount on 5.1 and 7.1 surround sound audio systems. As computer graphics get more and more realistic the quality of the computer's sound must improve now and many of us have seen that onboard audio simply cannot deliver without a massive cost of PC performance. Auzentech has recently released the X-Meridian 7.1 which is capable of delivering audio that will make your audiophile friend start drooling.
