i have a sound card that has a bunch of dts technology xonar dsx by asus and so i was wondering if i lost any performance by connecting to pc via spdif since the card and my speakers are dts supported. i have the Logitech z906. i am tempted to use the actual aux connection from the sound card so i can use the card to its potential but dts sounds tempting i want the best possible audio experience so i ask what is recommended in my case
