Be careful with high-end discreet audio purchases. Many mid-low end cards have all the features you want (3d audio, EAX, etc.) for half the price. In the past, I've bought the creative "gamer" line because it had exactly what I needed at a fraction of the price of a "Fata1ty Uber OMG FTW Live!" card.
As always, do your research before you buy.
Some of you just don't get it, do you?
These "FEATURES" you speak of.. you don't NEED them.. 3D Audio, EAX emulation, etc.. are not NATURAL, and are not what determines high quality sound. They seem to serve as nothing more than marketing buzz words, which apparently work just as successfully as the "fat4l1ty" type of advertising you are criticizing. Many of you actually think this stuff matters.
The hardware matters.. the DAC, the DSP, the opamps, etc.. THEY determine your sound quality, and
not all are created equal.. If you have the high quality hardware, you don't want ANY of this artificial, emulation, simulation, manipulation of sound, etc .. its all nonsense and for me, completely undesirable.
And the speakers/headphones are of course the biggest factor. The higher quality speakers, the more you'd benefit from say a higher quality DAC and higher quality amplification and even sources like FLAC, SACD, and Vinyl.
Price; There's no reason, NONE, to buy a discrete sound card especially on the PCIe bus when you have a well isolated onboard sound card available for essentially free.
I don't know how you can even make this comment, with the overwhelming amount of people, even with the totally entry-level Asus XONAR card, claiming they heard very significant differences over onboard.
In fact, it seems like every person to ever pop in a good sound card has reached that very same conclusion unless they went ahead and outputted digital, rendering the sound card useless anyway. Although I do realize we have a lot of people who do this though.
Do you think we're all just falling for some crazy placebo effect or something? Because all you have to do is go BACK to onboard sound after running a good sound card for a while, and you are immediately greeted with a pronounced dull and lifeless sound quality.
