If you're on a PC:
Metric Halo does not work.

There are many other options then, but I am as confused as you by their amount, so I better shut up.
If you're on Mac:
ULN-2 is even more expensive than FF400. But it fits the needs you have and has certainly the sound quality you are looking for.
Apogee Duet is way cheaper with comparable sound quality, but it is lacking digital I/O. If you could do without digital, Duet would be the best option.
