Technically, not quite. The dual mono is meant to imply that the signal/ground in the LD amps are not shared in the amp circuit apart from being paralleled through the connectors. Balanced is a true dual mono design, where each ground is actually a mirrored (well, negative phase) of the signal which yields double the voltage swing. Regardless, the ground in the MKV is an active ground, where small currents are grounded to the PS ground but large currents (like the return from the headphones) are handled by another channel that sources a constant return to ground.
Also, seperate PS's. Almost forgot about that.
