I've used this usb soundcard in the past and although I noticed differences in sound profile, it did not feel like an improvement over my on-board sound (ASUS MAXIMUS VII GENE. It says SupremeFX Impact II audio card. I don't know what the chipset is). After a few months, I did not like the extra clutter on my desk so I sold it on kijiji.

What do you think of that? Am I just not an audiophile to notice the difference in quality? or was that usb sound card not good at all?
