Once again, it's not all about ones and zeroes. I went thru onboard sound, several driver sets, a Creative EMU, an Asus Xonar, ... etc. before finally going with an outboard DAC and ADC. There's just too much competition for resources inside most computers. Even then, the only way to clean up some leftover garbage was to get a dedicated USB bus card with it's own tap direct to the power supply. I use that ONLY for the DAC and ADC.
Just saying ...
THIS IS THE (oops ... my bad ... turn it down a bit)
This is the voice of experience!
Prepare to be disappointed or lower the bar. Both cards I tried were alleged premium options. The Xonar was just ... not right, and the EMU was just flaky - Hardest part was uninstalling it. Took some serious pillaging in the registry to put a stake thru it's ugly digital heart. Persistent little cuss too - found out every time I made something go away it was dialing home and downloading more until I disconnected.
Then again, yall might just get lucky. Hey ... it could happen!
