If you are playing a passive bass, I recommend using a DI in line to boost the signal so you can take advantage of a more full tone. I still use a DI even though all my basses are active though. My previous interface also had me go through a PreSonus TubePre for some coloring. The result was a really beefy sound, so if that's what you're looking for, you can use something like a SansAmp or other coloring device to give you the tone you want.
