With the tubes I have in place now, bass boost is unnecessary for the HD800.
But in answer to your question (TMI), the main reason the HD800 is on my head first this time is that the LCD2 is upstairs ATM
I was trying it in the new/old bedroom rig, as it has the power and the tonal balance for the LCD2, but it was a no-go. I'm guessing that it was an impedance issue, will have to find my stock HD800 cable and try those next. If there's an issue with that combo (BC DAC2 > XCAN/PSU) it will be tonal balance and not impedance. It sounds great with the HD600 but a bit sharp up top, would like to give the HD650 another shot in this rig at some point.
