I have fully differential mono-block power amps where the 1st and 2nd stages are direct coupled. Voltage offset in the output of the 1st stage is avoided by the use of a CT plate choke and a reasonably balanced 6SN7 (necessary for the choke) for the first stage. Low DCR of the choke and small imbalance current take care of that.
