i have recorded an album at home using the digi001 on a PC - i want to do some simple lo-budget mastering at home using Samplitude - and outboard gear (rnc 1773 compressor and BBE sonic maximizer) - what role does a/d, d/a conversion have to do with this (my knowledge is somewhat scarce about this)

will i need to buy a decent a/d d/a converter? or by running out/in of my 001 box will it be okay for the level I'm doing things.

thanks in advance for any help - and happy new year to all.
