Thanks for the clarification. I based my comments on your original statement where you said you recorded at 44.1/16 and did no processing.
I'm not sure if the dithering is necessary if the audio temporary goes through higher bit depths, but I might as well be wrong.
Also, I'm not sure how the dither affects the following conversions to lossy formats like mp3. Bouncing the tracks in Logic Studio
allows you to dither only if you bounce to wav of aiff, with mp3 or aac it's not possible. I've read somewhere that those encoders
have their own dithering systems. If this is true, then it would be optimal to make the mp3 (or aac) directly from the DAW, not
exporting a WAV first (with dithering) and then converting that. But again, this goes to the guessing category

Here's the reason why I always apply dithering as final step in mastering:
the 44.1kHz/16bit file is imported into Nuendo as 44.1/24bit session. Then different processes are applied, some of which involve 32bits calculations, some floating point calculations, that are saved as 24 bits data. To get down to CD Audio format again you have to reduce it back to 16 bit (even if there are no other processes like normalizing or other plug ins involved). For this dithering is IMHO a must. I use an excellent dithering algorithm by Apogee called UV22HR for this last step.
Please dont hesitate to present your arguments if you think I made an error in my assumptions or reasoning.
