Nothing dangerous, just degraded sound quality due to some complicated electrical issues.

Easy way to find out is to just blind test the DG against your onboard sound at a similar volume level. If the DG sounds noticeably worse, it's a bad match for your 595's.

I haven't found any exact measurements on the DG, (which I also use myself, but with 150ohm PC350's) but most people agree it has an output impedance similar to the other Xonar cards based off similar designs. (about 10ohms) Which means you probably will begin to notice degraded sound quality on headphones with impedance levels lower than 80ohms. The 8:1 ratio isn't an exact rule though, just a good guideline.
