This thread is special in a special way. OP, I'd recommend the Little Dot DAC-I. You can resample in software later, if you want to.
The thing is, I currently run 4 operating systems on 2 computers: Windows XP, Windows 7, Ubuntu Linux 10.04, and Mac OS X Snow Leopard.
I use foobar2000 on the 2 Windows installs, so I'm sure I can easily set it to upsample if I wanted to. It's the other 2 operating systems I'm worried about, as I've Googled around, but haven't found anything substantial or not outdated.
If anyone knows sure and easy ways to upsample in OS X or Ubuntu, then please let me know! I'm only considering the DacMagic because if I don't know how to upsample in a non-Windows OS, it's much more convenient that it does it for me automatically. Granted, I would also not get to turn off the upsampling...
