Ah, OK. I'll ignore the discussion about different sound cards influencing this as a heap of confusion and settle for this: If JACK would not have bugs, by design it would do bit-exact copies, or at least copies with floating point computation errors in non-audible amplitude. I don't claim that this ideal case is indeed the reality.

When you find those bugs, I hope they'll get reported and fixed, for the benefit to us all. In the meantime, those of us with some time on their hands can just try to verify the issue of bit-exact copying of data through the pipeline ... I just don't want to go down that path right now, since I'm already not able to do my actual work because of debugging some gcc 4.6 breakage on code of mine.

Alrighty then,
