I am hoping some people more in the know than me can help with this. I traded some unused computer stuff for a ASUS Xonar DX PCI-E sound card. Now currently in my main rig I have a Razer Barracuda AC-1 The razer works and all but I wonder if I will see a sound quality improvement with the Asus xonar dx, I hear they have the same chip, but what else, amp etc...? My current head phones are ultrasone pro 750s. I have various other computers that I can put the sound card in if it isn't much different in sound quality.
