What I didn't like (and it's not the card's fault) was lack of ability to upmix stereo. A customer answered my question pre buying it about that ability and assured me that it did, but it does not. It "mixes stereo" apparently, but that is downmixing on recording. And I found no way to refute his advice. Perhaps he was speaking from experience with a higher end card which uses a different version of the software designed for the different chipset in the higher end cards.
