If the high ac voltage of the Melquiades amp is what allows it to operate with the same coupling cap that doesn't work with the buffer, perhaps there is some hysteresis going on in the capacitor. In that case I think it may help to use a smaller coupling cap inside a feedback loop. The feedback should restore the bandwidth lost by using a smaller capacitor, and I think reducing the amount of dialectric would reduce the hysteresis.
Is there something to be gained by using such a low rolloff frequency?
