I agree Orpheon, audio is very subjective, different music requires different setups, some people require more bass than others, its all a matter of you and your hearing. For most people they couldn’t tell the difference at all from one card to the next.
One thing i will say, is that the Breaking in i did with my headphones made a huge difference. So much so it woke me right up, and im not a morning person. The difference was staggering. I can understand the debate though as most users will sit there all day with them on and not really notice the difference as its happening while using them. Some may not even need that much, or its in tones that dont need it. All i know is mine made a huge difference from breaking in or burn-in as some call it. Some people have said that even after a month of using these particular headphones they are still noticing better sounds, personaly after that first night of playing music through them ive not noticed any difference, probably because im now using them all the time and im not noticing anything different. In any case im one of those people that probably couldnt tell the difference anyway, im deffinatly no audiophile.
As far as brands to avoid, pesonaly i couldn’t say, you may have brands over there that we don’t have here and vise versa. I know there have been graphics card brands in the past that have been talked about by Americans i’ve met playing games, and from reading articles that we just hav’nt had here in the UK, and we have had some that the Americans have never heard of. They would probably be the brands that are small companies using larger company brands just to resell with thier names, so they are probably the ones to stear clear of. If you stick with well known brands, “most” of the time you wont go wrong, thats my way of thinking about it anyway. Creative and Asus have always been one of my favourite brands for audio… so far anyway.
