After ten years of playing RPGs, solo and MMO, I have got rather bored with gaming and, after a fifteen year hiatus, have got back in to listening to music. I have recently bought a pair of AKG K550 headphones, which are excellent but, have done a fine job of exposing the weaknesses of my gaming oriented Creative Sound-card. After much thought and reading reviews, I have decided to stay with a sound-card, rather than an external solution, as I don't need portability or more desk clutter. It also looks like I can get more quality for my money. I am considering buying an Asus Xonar Essense STX but, would like to know if anyone has experience of this card, or another recommendation. My budget is up to £150 but, within that limit, quality is more important than price and I intend to keep it a long time. The Asus is £147 on Amazon.
