I think with firmware version 2 this is possible. before v2 firmware on the DT50, you only got sound from the direct output when the amp was fully on, which meant you had to have a cab connected. The DT25 didn't used to be like that, and so the DT25 feature has been ported over to the DT50 fo rrunning out of the direct output when in standby with no cab is possible.
As I understand it, usually most tube amps only warm the tubes up when in standby. that's the whole point of standby. So the higer voltage that runs the tubes fully isn't applied until the standby switch is moved to the on position.
The down side of this is that if you accidentally flip it to on with no cab, you could blow your amp. But if you're careful not to do that I think you should be fine.
