I would agree with you it is king, but based on Watts/dollar only. It doesn't have much storage capacitance at all, didn't you read Gene's review, though you did so you must have missed his point on the cap.
In my opinion, the Outlaw 5000 is like an AVR on steroid in terms of current output capability. (sorry, I am beginning to hate using the term "power", that makes little sense for reactive loads).
