I'm not sure here, but my thinking is this.... if you want to bi amp the Warfdales, a splitter of sorts is going to be needed. Perhaps just a Y connnector, and two sets of ICs. one pair for each pair of amps going out to the spakers, plus two sets of speaker cables.... one for the top, one for the lower end.
As long as the Xover in the Warfs is in atct and not defeated somehow, I don't see how a tformer is going to help. As whatever signal is run into them their Xovers are going to cut off at whatever level the signal being fed to them.
Re balanced
I'm guessing here... if a signal is incoming to the pre/proc via SE, it is still a signal. I could then see how it would be passed on via balanced topology.
I could also see how that would not happen.
Call the maker (s) of the pre/proc and ask them.... both questions.
