I'm sure Lynn will flesh out all the details, but these questions come to mind:
What were the tracks recorded to originally? I'll assume into a DAW, but which one?
Was any processing be applied on the way into the recorder?
Did the tracks go through a console or from outboard preamps, and straight to the recorder?
I expect the differences, or lack of differences, will not be affected by several of the answers to those questions, but the details are important. The effects of summing will either be discernible or they won't. That's my guess, and I'm very interested in having a listen to this project.
