I have received the Indigo IOx (Express Card) and installed it. It has somewhat better sound than the Behringer USB card I was using. The user interface is very nice with the capability of using 4 stereo inputs and mixing them for one audio output. Not sure how I could use that feature, but nice that it's there.

I had hoped that I could eliminate my isolation transformer and not suffer ground loop noise when connected to external equipment, but that wasn't the case. But without being hooked up to external equipment it is dead quiet when not playing a track.

All in all I am quite happy with it and picked it up from Full Compass for $129, a very good price by comparison with other sources.
