Thank you for your suggestions
I have taken a look at the Audiophile soundcards. They cost $100 (if you're lucky) and up. I guess I could perhaps stretch my budget to that mark, but the most pertinent question if I do is:
Would I hear the difference? I do not consider myself audiophile (although I do appreciate good sound) and I am not planning on making music, just
listening to it.
Or, if we are talking about for example Creative Audigy - would that be a step up from my integrated card? Because I can see that they go for under 10 bucks on eBay. As do C-media cards.
