Does anyone own the Crown K2? The specs on this thing are incredible. They take less volts out of a wall outlet and transfer the power to the cabs more efficiently. A perk of being so efficient like this, there is no fan and it is 2 rack spaces. Sounds like an incredible boost over the Carvin DCM2000 I've been wanting. Forget about the price. Does anyone know any poweramps that can get very efficient wattage usage, too? I'm trying to keep my choices with toroid-transformers because they maintain the low freq signals better than for say a QSC PLX, as I've heard.
