The cross coupled phase splitter can handle the same voltage swing as the equivalent plate loaded stage. Assuming reasonable balance, half the difference between the input voltages appears at the common cathode and the output voltage is the gain of the second triode times the difference between its grid voltage and this cathode voltage. If you do the arithmetic you will see that this makes it capable of full output swing.They can also be balanced to any degree of precision required by ensuring the first triode of each pair has more gain than the second one and then reducing the gain of the first by reducing the cathode impedance. The only limit on the balance obtained this way is capacitive bypass at HF.
