thats my current setup now, GV + Gizmo5 on PAP2 ATA and have enjoyed it for about 1.5yrs with no problem. I do many conf calls for work on it, its been awesome, but as you said, Gizmo5 is about to shut down at end of this month, so I'm scrambling on the alternatives, then I came across this Obihai, so I'm doing my research now before I commit on it.
