I would try grabbing the low hanging fruit which I mean powering the components that have external wall warts with smaller lithium ion battery power banks. Usually that means the dacand a streamer, Sometimes a preamp. This is a good way to make cheaper components so much better. Your larger components that are built for AC power do not lend themselves to this approach as has been explained above
Duracell 660 Powerstation to Run my System off of the mains?
What do you think? It's a basically a huge powerbank. Would using this between my wall outlet and my Furman power conditioner basically be like separating my system from my home electrical system and be like running the whole thing off battery power? I mean that's what it would be doing, or am I missing something about power conditioning and supply?
