I just got this sound card in the mail yesterday and it is my first departure from on board audio. I must say that I am somewhat disappointed. I was expecting (hoping for) beautiful crystal clarity, which is not what I received.
I can't say, however, that all is the same, so I will list them here:
1. The biggest difference that I've noticed so far is that I can turn up the volume without my ears hurting. I don't know what causes this, but I'm pleased in this regard.
2. No unrelenting 'noise'! This much was clear the moment I put my headphones on. At first I thought something wasn't quite right, that the audio wasn't working because this 'noise' has become so familiar to me, but all was well. Now, I don't hear ANY -- at all!
3. The lows are much clearer now. Previously, I found bass to be a bit of an annoyance, like being lightly punched in the side of the head. Part of the problem, perhaps, was that the on board audio didn't differentiate between the notes well at very low levels; it all mostly sounded the same -- and rough. I suppose it may be called "muddy"(?).
4. The mids no longer sound so suppressed. I wouldn't say it sounds as upfront as the highs are (with my ATH-M50s), but I no longer have to use the mixer to boost it. I've since returned to a flat equalizer.
Dolby Headphone. It's... good.. I think. I really can't decide whether I like it or not - at least for music. I haven't tested it (or GX) thoroughly in video games. Only briefly.
In the end, I was truly hoping to find a difference as clear as night and day, but I would say there is no difference in clarity, spare for the lows. Maybe my board just has good audio; I do recall that when I was reading the reviews prior to purchasing, it had good reviews in that regard. It's an Asus P6T, FYI.
And that's all I have to say about that. I know I read once that sound cards have burn in as well, but when I searched for any more information in the matter, I came up empty-handed. Maybe it was just one mad man's ravings.
The sound card is physically a beautiful piece of work, however...
