I had an Audigy 2 ZS in my machine yesterday. Last night it was ripped out and in its place went an Auzentech X-Fi Prelude 7.1 Gaming Sound card. OH MY GOD! I was hoping there was going to be an increase in quality over the Audigy, just moving up to the X-Fi range and I have to say this card has blown my socks off. The quality of the sound produced is absolutely shocking, its like someone has cleared the wax from my ears and I can hear properly! The clarity is amazing! So far all I have had time to do, is play a couple of Star Wars mp3's ripped from the original soundtrack. It was like an orchestra in my bedroom. I can't wait to try a few games and more tracks later!!! Anyone else got one yet, I got mine from MediaAtlantic: http://www.mediaatlantic.com/auzentech I am well chuffed so far!!!
