When we developed the MP-1 back in the late 1980s, there was still a lot of single-ended stuff around, so we set it up with SE recording outputs and SE monitor inputs, despite the preamp being otherwise fully differential and balanced from input to output (and was the first such preamp).
We've often run into a similar issue with owners of Merlin loudspeakers. The Merlin uses the BAM, which an external bass EQ unit. We usually have the customer run the BAM on one of the Monitor loops and that seems to work quite well.
With a preamp such as this you could run balanced from all your sources and balanced to the power amplifiers and simply hook up the existing BMC.
