Hiya guys, I bought some new earphones for my MP3 Player (MusicalFidelity EB33's) and they arrived today, and are amazing, tried them on everything and they sound awesome, except on my PC, they sound tinny, and very analogue...if that makes sense. I predicted this after doing research, and already ordered a highly recommended sound card which also just arrived, an Asus Xonar DX. Just installed it all, and while the sound via speakers sounds better (albiet with a small background constant hiss, not sure what causes this) the headphone quality is just the same! I was expecting a jump in quality, at least on par with my MP3 Player, but it's exactly the same as before I fitted it, have I just wasted £55? Or am I doing something wrong, I have tried connecting directly to the card, and via the front panel which is hooked upto the sound card and the results are the same.
