Just wanted to say thanks for the advice I got a while back with respect to headphones. I ended up going with some Senheisser HD555's and all I can say is... holy crap. Even shitty mp3's sound better with these things. I just got my x-fi card in as well and I've started downloading a ton of flac .
Awesome stuff. Now I'm curious to see if the higher model headphones can make this even better .
One question though: What should my soundcard settings be like? I mean, should I turn up the volume in my computer as high as possible and then control the headphone volume using the soundcard (it's an external one).
