So...I just got my reinhardt which has power scaling. I wasn't sold on PS after my initial foray into it. However, i'm really sold on it. I'd like to A/B it with an ultimate attenuator but at this point, I would say that it's perhaps the best way to get the cranked amp tone at lower volumes. The reinhardt amp clip I posted in the demo section yesterday utilized power scaling. I had the master and preamp volumes at about 2 O'Clock and the scaling at 12 O'Clock. Sounds pretty much like a cranked amp to me and the actual room volume was relatively low.
