I'm curious, given the 744t has just one pair of channels with internal preamps, what advantage does the 744t have over sync'ing say a couple of 722s or a 722 together with a 702 (or even a 702t for time coded files), which together runs a similar cost but gives two sets of internal preamps.
One obvious answer is that the 744 is smaller than the duo. What else?
(Edit to note that even though there is a smaller package with only one 744, it's offset by the fact that you need to carry an external preamp to run all 4 channels, so doesn't seem like much of an advantage to me.)
