rowuk , you are not wrong feeling that what we do with PS and Mains regenerator is kind of ridicules. Indeed we convert AC to DC, then to AC against and then to DC again. If you use SS then it very much makes sense to run DC directly to B+. I know of guys from Eastern Europe who run tube electronics, ironically high voltage direct heated triodes and they power +850 directly from batteries. Yes, I feel it is “elegant: solution but I feel that there is no future behind this approach. It might work for some kind of boutique installation but universally it would not work. Now, would it be fun if ALL let say digital devises have a mandatory +12V power entry and PS switch internal/external? 
 
Saying all of it I am not sure that running batteries direct would be problem-free solution. The guys who do run batteries report own unique problems. I personally would not explore this direction. What I would love to see instead of going for batteries would be a unified theory of power for Audio or some kind of knowledge that would explain what is relationship between Sound and Power. So far we just tweaking power and not truly know what we do. We accidently catch better result and we think that it was it. I hope our structural engineers and doctors do not use the same skill set…

Class D amps are cheap enough these days, maybe I need to build a power supply with built in regeneration? Maybe I need to think about impedance on the primary side of the PS transformer.
I am not particularly interested in batteries. I tend to leave things on for a while when I am in a listening mood.
