first,to the OP, Great! insightful question. And, in both theory and reality, yes.
now, practice is the hard part. Back in the 80s, a friend and ex business partner suggested and ran, so "battery parties" where 8+ folks would get together and donate, for a while, car batteries so we could get + and - 48 Vdc with stupid hgih current (commenting on a sub thread above).
Sound: superb. Practicality: Zero. But that was 40 year ago.
Today, for low power draw products, Lithium Ion batteries are a great way to go - but probably you will have to roll your own. Charging is nto as simple as hooking p 12 (or whatever) volts.
It is quieter. "blacker" as one put it. And more nuanced and dynamic. Compared to a really good power supply, its very subtle. Compared ot the typical one, well.... your definition of typical may stray from mine. I'm not impressed. Everything I build a power supply for gets way better. Off topic note: wait for my rant on an Intel NUC as a ROON ROCK server, and the lessons in reality i learned.... but i digress.
It will be a project. but the end goal may prove worthwhile.
