Without dithering, everything past 16 bits is thrown away, which will sound poopy. Not to mention down sampling from 48k to 44.1k (if you don't re-sample, going from 48 to 44.1 will make the recording slow down significantly).
"poopy" in the technical definition of "what digital recordings sound like when they are downsampled to 16 bit without dithering." I think that's in the Rane lexicon.
