Honestly, I wish the Turtle Beach guys had taken Nvidia up on the offer when they were approaced for making a standalone Soundstorm card (considering I'm only connected through s/pdif, so don't have surround sound gaming). However, Turtle Beach is exiting the pc card market (as you can see from their product line) so turned them down. I'm sure Creative acquisition of Sensaura will only make things worse....
Personally, I have a great deal of respect for those that designed the TBSC card. It's elegant, and has great quality of hardware / software (which shows when we still talk about buying it today).
