Hi there, I use my pc for pretty much nothing but gaming, specifically Battlefield 3 at present and always use headphones - Razer Carcharias. I quite like the headphones, I find them to be very comfortable and I think their sound output is good (though I must admit I haven't got much else to compare them to). Regarding my soundcard, I've got an Asus Xonar DG but was looking at possibly upgrading to the Essence STX. It's quite hefty at ~£140 so wondered whether this would be a worthwhile upgrade. What I'm looking for really is an even more immersive experience and the ability to maybe hear more than I can at present (for example, I like to try and hear out where my enemies are coming from). I've done a lot of research and am still a bit confused. I heard one fellow state that there is not much difference in quality between the DG and the Essence STX. However, I'm sceptical about this because the DG can be had for less than £30 whereas the Essence is over x4 more expensive. Some advice or recommendations would be highly appreciated.
