On the Mark 2, it is said that only 1 of the 2 outputs can be used. One is Transformer, the other is OTL (output transformerless). On my Mark 3, both outputs work at the same time, and i have not tried cans with different impedance, so I can't help you out there. Also, on the Mark 3 the power supply is outside of the unit.
