Curious as to why shouldn't you try to drive two pairs? I've powered both the HD800 and LCDX at the same time without breaking a sweat. This puppy has 6 discrete amps in it for a reason. 2 for 4pin, 2 for 3pin, and 2 for SE. The SE is the only one that shouldn't be split... FYI, the power is divided between the two HPs, whereas in balanced, the power is not divided.
I couldn't be wrong, but I'd like to think I'm not
No, the SE can be split. It's the balanced output circuitry that should not be split to two HPs, simultaneously thru the pair of 3-pin XLRs and the one 4-pin XLR. At least That's what I've read.
