Hi For a year or two i am using Creative X-Fi Platinum. But now is time to upgrade my source because i think that X-Fi is not very good card for music. I don´t play games any more. Or maybe 5% of all time spent on PC. So performance in games is NOT important. Now i wan´t to improve the sound quality for just listening to music. But i actually don´t know what will be the best option. I was thinking about: - Auzentech X-Fi Prelude (last option) - Asus Xonar - E-MU 0404 - M-Audio? Or is there any good alternative? What about usb dac? Wich one? So what is the best choice? As i said i need to improve sound/source.
