Welcome to PureOC!!! Glad you decided to ask your question here.
I can not think of any sound card that works pci-e x1 that is worth looking at outside of the ones you already listed. I know you have an aversion to CL but you have to admit they know what they are doing. Been doing longer then anyone else. If I had to pick another I'd go with the Sonar DX.
Hope you share some pics of this rig.
