I just want to add that I think that you're thinking very clearly of a high power unit.
I was told by three different audio component manufacturers that, like a power amplifier, the more power, the more headroom for dynamic bursts and an easier handling of the load on the unit.
All three said to allow a 10x power handling capability, and I found that to be true. I started with a 1.8 Kva unit, then a 2.4, then 2.5, then 3.0 and finally a 5.0 Kva unit. I only had two components on mine, and when I finally put the 5.0 Kva, the soundstage opened up and expanded, as well as the decrease in the noise floor and a lot more micro details emerged.
