why is there any phase splitter in the circuit?
Now I see why, having re-read your post. But I am not sure why you'd need two different input voltage amplifier/driver stages, one for balanced and one for SE operation; a balanced input can be driven in single-ended mode (just ground one side of the balanced voltage amplifier) and the output of the balanced stage can then drive the output stage in balanced mode, thereby obviating the need for a phase-splitter. But I guess there are many ways to skin that cat. (Metaphorically speaking; I do not endorse cruelty to animals.) Seems unnecessarily complex is all. The Atma-sphere amps are designed and operate as I've described above, for one example.
