I'm sorry! I now see that you're using a Mac Mini. This computer does not have a PCIe slot so the Adnaco-S3B is NOT an option. There is a solution that connects to a USB 3 port but I don't know anything about it's quality. (http://www.adnaco.com/products/su1/)
The Stello U3 is merely a USB-SPDIF converter for DAC's that don't have a USB input. I have no experience with this device but I think the Devialet provides a much higher quality USB solution.
