I was attracted to the idea that it was an attenuator/reamper, which meant to me that the tube power section was designed to "stay out of the way" of the cranked amp sound running into it. Seemed to me that it would treat the sound from a modeler the same way.

I run the 11R Amp Output Level at 0dB, and the physical Amp Out 2 (rear panel output) at max (+12dB). With the Power Station at unity gain, presence and depth at 0, I get what feels like a pretty close full-volume representation of the amp being modeled. From there, I can drop my stage volume down using the PS level control, adding presence and depth as necessary, just as if I were attenuating a cranked amp. Works great!
