This is an interesting approach, particularly the higher order realizations. To some extent I think the declaration that the capacitors are not in the signal path is at best semantic. I do however follow the early argument for the benefits of eliminating the input coupling caps for an inamp and their imbalancing effects. Also, one of the drawbacks of higher Z in the discussion of making the capaictors smaller is not mentioned, namely the increased noise. Of course there is only so much space.
