But there's a time delay in getting that feedback signal to the input


WRONG again.

Oh, maybe 20uSec, but maybe not worth worrying about?

You think that the open-loop bandwidth of a typical op-amp is only 50kHz ?

Try 55MHz for the LME49710 and around 10 MHz for more pedestrian offerings.

It's NOT a *time* delay either.
