Default Transformer input for Hafler 9505?

As far as I can tell the 9505 isn't a true balanced input, but relies on some buffer
amps arranged like instrumentation amps which adds another stage which doesn't
perform any gain. I have several of these around:
and was wondering if this would be a better approach and if so,what the best way
to disable, bypass, wire input stage would be. I have some of these in CI-2RR as well :
that I am driving Acoustat TNT-200 with from TNP preamp and like the sound, so I
don't think the debate of "transformer distortion" is not what I am seeking.
Just is it feasible and "how to".
I do have the 9505 schematic but file was too large to upload.
I also have some of the of the low freq. tranies:
and have considered using the 9505 as sub amp.
