Sharp/Slow rollof, De-emphase, PSU

I'm playing with a PCM1794 dac.
I have several issues I can't find a good awnser for.

First one:
- What's youre recommendation on the dac filter, Sharp or Slow?

- I understand the principals of pre/de emphasis. But on an DAC, does it needs to be on?

- The application circuit states two 10uF caps near the DAC chip on the analog 5v line.
I have implemented a Shunt regulator and the shunt designer states that I have to remove any caps after the regulator.
Can I remove the caps near the chip?
