Hi!!
My current setup is: 
Radeon hd6770 graphics card connected to PC Monitor(full hd LG) via hdmi cable. My Sr60 are connected to PC Monitor. 
Spec. of video card:
Integrated HD audio controller
Output protected high bit rate 7.1 channel surround sound over HDMI or DisplayPort with no additional cables required
Supports AC-3, AAC, Dolby TrueHD and DTS Master Audio formats
I was thinking about upgrade for my headphones, but i have no idea if buying for example Audiotrak Prodigy Cube Soundcard will be any improvement over current setup i have.

So really, your monitor is your audio source. It has a built-in DAC and amp.
I can't help with your question, but others will no doubt want to know your monitor's model.

Thnx for reply. Unfortunately i cannot find any info about quality of DAC inside monitors.
Monitor's sound output sounds good but I wonder how good it actually is compared to a USB DAC?
