Interesting, interesting. Are you sure the bounce files are in exact sample-accurate sync with each other? The AES/EBU -loop may have introduced a delay.. You can check the exact start positions in the sample editor. Another possibility I can think of is dithering, added by some device in the AES/EBU -loop (what kind of loop was it exactly?). In that case, there's nothing wrong with Logic's bounce, it just won't add any dithering unless you tell it to (there's a plug-in for that). In any case, I think dithering should be added only to the final 2-track mix, not to any submixes or bounces. When you mix multiple audio tracks into a 16-bit audiofile, there really isn't so many ways to do the mixing. It's a very simple and straightforward mathematical calculation (you just add together the signed sample values of the tracks). I don't understand how different programs could do it differently? The only exception (according to my knowledge) is dithering (or noise shaping), which makes the mixed result sound better by adding a little amount of noise.
