Except when CAug7 means CMaj7(#5). Have you been reading these posts? Read what I said in post 77 and reiterated in post 78. Now, I would make the argument almost from a tertian point of view that it actually does make more sense that a Aug7 chord should mean a M7 based on the fact that having a b7 creates a suspension between the #5 and b7 rather than the tertian interval between the #5 and M7. It is only because I can see that for the most part Aug7 would be taken to mean a b7 that I don't enforce that view. So for the sake of ambiguity I would write those two chords as I said before.
