so i have:
DT 770 PRO 250 OHM closed back headphones 
Xonar Essence ST pc audio card with the built in 600ohm apm.
the gain setting on xonar card is 60-300 ohms.
 
i use the unified xonar drivers from here:

with this set up the windows volume is at 19 for most use (gaming and such) and maybe up to 35 if i want really loud music.
at 19 there is just the hint of a hiss. can barely make it out if nothing is playing. do not even notice it with stuff playing.
at 35 its very audible, though not when stuff its playing.
100 is very loud.
 
anyone have any ideas?
thank you for your time

No problems.
 
Yeh sometimes you do get weird artefacts with non-official WHQL certified drivers (i.e aftermarket or modded drivers), the same problem I got when I tried forcing a pair of old Creative X-fi's running in Windows 7 using modified driver packages, the result was massive distortion. Then the official WHQL driver was released and rectified the problem right away.
