A quick Google shows the DAP has a DAC Out, so you should be okay with using a separate, and hopefully higher rez DAC.
The separate DAC would use the information provided from the source, so if you are streaming a high rez signal, it should pass it onto the external DAC. If you are using a Redbook CD, then you are limited to 44.1khz, but an external DAC, especially a newer model, will probably give you better resolution/sound, as DAC technology keeps getting better with each passing year.
Can you tell us what external DAC you are considering?
